Definitions
- the present application relates to a novel adhesive composition, and a method for preparing the same.
- Adhesives generally use petroleum-based monomers and oily solvents as raw materials.
- Monomers made from petroleum-derived raw materials and pressure-sensitive adhesives formed therefrom have problems of reduced production due to petroleum resource limitation, environmental hormones generated during manufacturing, and toxicity at disposal.
- organic solvents derived from petroleum are used in the manufacturing process in order to improve the adhesive strength in the conventional adhesive manufacturing, which impairs the health of workers and has environmental problems in terms of environmental protection.
- most adhesives are difficult to decompose naturally because the monomer units are made of covalent bonds, and environmental pollution problems are also raised by polymers that are not decomposed. For this reason, techniques of various water-separable pressure-sensitive adhesives for effectively removing the pressure-sensitive adhesive from the adherend have been developed.
- An aspect of the present application is to provide an adhesive composition.

- the term “adhesion” refers to a phenomenon in which two objects (but not gas) are in proximity and then require some force (or work) to pull them out. In some cases, some materials having adhesion may become solid after a certain time after the substrate is applied, and may be accompanied by irreversible physical breakdown if the adhesive is to be separated from the substrate. In addition, the “adhesion” may include "viscoelasticity", which requires some force for viscoelastic deformation when the adhesive material is separated from the substrate. The adhesive composition having a viscoelastic property is stored and distributed through a general processing form before being applied to a substrate, and its adhesion can be maintained even after a certain time.
- Examples of the adhesive article obtained by applying and drying such an adhesive composition on a substrate include a label and an oriented polypropylene (OPP) tape.
