The substanoesof the first addition agent class, the alkylene amines, -are-:soluble.to the extent of at least 0.0001 gm. per, liter inthe plating solution (for example in a solution containing 240 gm. per liter MSW-611203315, em;.;per liter .of NiClaGHgO, and 3715.5, gm, per -liter sBQaremainder. water) and are ezha ins; qle ula wei h IIQm- O to 1800 or higher, preferably from 600 to 1800.
The general formula; for l the unsubstituted alkylene amine compounds is as follows:
where m is an-integer from 2 -t0 4- inclusive, and n is an integer greater than=2, preferably 12-150 40. Not only unsubst itutedlalkylene. amines but also alkylene amineshaving substituents on the nitrogen, replacing hydrogen thereon maypbe. utilized within the imoleculanvweight limitations set forth above.

The alkylene amines lower than tetraethylene pentamine are not very effective unless substituted so as to bring up the molecular weight. Numerous compounds can be used, as indicated, for increasing the molecular weight, and the substitution products are often somewhat superior to the forms of lower molecular weight. This is true even of tetraethylene pentamine, which, although a good brightener, is improved by increasing the size of the molecule.
The carriers or regulators constituting the second addition agent class are soluble in the plating solution (for example, in a solution consisting of 240 grams of NiSOr 6H2O, 37.5 grams NiC12'6H2O, 37.5 grams of 1131303, and water to make a liter) to the extent of at least 0.2 gram per liter. These include such materials as benzene and thiophene sulfonic acids and salts thereof and halogen, methyl, ethyl, CH0, and phenyl substitution products of the foregoing, such as for example:
Carriers or regulators Benzene mono-sulfonic acid (C6H5SO3H) Benzene disulfonic acids (CsH4(SOsH)2) Sodium benzene monosulfonate (CsHsSOsNa) Nickel benzene monosulfonate [(CcHsSOs) zNil Monochlor benzene monosulfonic acids (C1CcH4SOsH) Benzene monosulfonamide (C6H4SO2NH2) saccharine, sodium salt (CsH4SO2CONNa) Dichloro benzene disulfonlc acids (C12C6H2(SO3H) a) 9. 2,5-dibromo benzene sulfonic acid (BrzCsHaSOaH) 10. Toluene sulfonic acids (CHJCGHASOIiH) 11. Benzaldehyde sulfonic acids (Cal-I4 (CI-IO) SOsH) 12. Diphenyl sulfonic acids (CeHCcH4SO3I-I) 13. Benzene sulfonyl chloride (CsH5SO2C1) 14. Para chloro benzene sulfonamide 15. Xylene sulfonarnides ((CHa) zCtHsSOzNI-Iz) 16. Para toluene sulfonamide (CI-I3CsH4SO2NI-I2) 17. Thiophene sulfonic acids (C4HaS.SO:I-I)
18. Diphenyl sulfone (C6H5SO2C6H5) I 19. Naphthalene-1,5-disulphonic acid 20. Sulfonated naphthalene. (Mixtures of naphthalene sulfonic acids, produced by treating naphthalene with oleum, preferably 2 parts of 20% oleum on one part of naphthalene at 160 C. for two hours) 21. Alpha naphthalene monosulfonic acid 22. Beta naphthalene mono sulfonic acid 23. O-toluene sulfonamide 24. Chloro naphthalene disulfonates Potassium and cobalt salts are useable as well as the sodium and nickel salts indicated above.
From these examples it becomes clear that numerous single ring compounds containing the effective group can be used, whether aromatic,
such as the benzene sulfonic acids or heterocyclic with aromatic characteristics, such as thiophene sulfonic acid. Various substituents on the ring structure are exemplified.
It is to be understood that all statements made herein concerning the capabilities of the addition agents presuppose the use of one or a mixture of two or more from each class. The carrying agents produce a degree of brightness without any brightener but not enough to be satisfactory alone. I prefer the use of the more common and readily available compounds, and prefer to employ in each addition agent class only compounds devoid of the group which characterizes the other addition agent class.
The constituents of the bath according to the preferred practice of the invention are (1) water, (2) nickel sulfate, nickel chloride or nickel sulfate with nickel chloride, (3) an aromatic sulfonyl compound such as an aromatic sulfonic acid or a nickel, alkali metal, or cobalt salt thereof, an aromatic sulfonamide, or sulfimide, or a mixture of a plurality thereof, (4) a wettin agent, and (5) a polyalkylene amine or a mixture of polyalkylene amines. An additional ingredient of the solution which is desirable is a buffering agent such as boric acid, formic acid, ammonium sulfate, or the like.
It will be noted that in respect to major constituents, the solutions are similar to the well known all sulfate, all chloride, and sulfatechloride or Watts type nickel plating solutions. It will be noted also that as to the aromatic sulfonyl type of addition agent or carrier as it is often called, the group of suitable materials are of the type which is represented by well known carriers in the bright nickel plating industry. The essential novel feature of the present invention is the use in such solutions of a small amount of a polyalkylene amine or a mixture of polyalkylene amines of molecular weight from about 100 to about 1800 or even higher.
The preferred basic solutions in connection with which my invention is realized are as folows:
All sulfate All chloride NlClz.6HzO 50 to 250 gms., preferably 100 to 200 gms.
Boric acid 0 to 00 gms., preferably 10 to gins.
Wetting agent (e. g. 0 to 5 gms., preferably 0.5 to 1.0 gm.

Wetting agent (e. g. so- 0.5 to 0 gm, preferably 0.05 to 0.15 gm.
dium lauryl sulfate).
To each of the foregoing basic solutions I add a suitable quantity of each, or a mixture of two or more of each, of the two cooperating addition agents. One of said addition agents or mixtures is one of the aromatic sulfonyl type and the other is of the alkylene amine type described above. The solution should, for best results, contain an anti-pit agent although the deposits may be suitable for some purposes without eliminating the pitting and, under some conditions, the deposits may not be objectionably pitted even in the absence of an addition agent for control of pitting. Sodium lauryl sulfate may be used as an antipit agent, although, as stated, its use is not essential and other wetting agents or mixtures of getting agents may be used for control of pit- The following specific examples will serve t illustrate the invention;
