Experimental Example . Evaluation of physical properties of colored photosensitive resin composition

[Production of color filter]

The prepared colored photosensitive resin composition was applied on a glass substrate (# 1737, Corning) by spin coating, and then placed on a heating plate and held at a temperature of 100 ° C for 3 minutes to form a thin film. Subsequently, a test photomask having a pattern for changing the transmittance in the range of 1 to 100% in a stepwise manner was placed on the thin film, and an interval between the test photomask and the test photomask was set to 1000 mu m, and an ultrahigh pressure mercury lamp (USH-250D, (365 nm) at 40 mJ / cm 2 under the atmosphere. The thin film irradiated with the ultraviolet rays was developed in a KOH aqueous solution of pH 12.5 for 50 seconds using a spray developing machine. The glass substrate coated with the thin film was washed with distilled water, and then dried by blowing nitrogen gas and heated in a heating oven at 230 ° C for 20 minutes to prepare a color filter. The pattern shape (thin film) thickness of the manufactured color filter was 2.3 to 2.8 mu m.

(1) Undercut measurement

The thickness of the pattern shape (thin film) was 2.5 占 퐉 or more, and the substrate was fabricated based on the color filter manufacturing method. Prior to heating for 20 minutes in a heating oven at 230 占 폚, SEM photographs were compared and the difference in undercut length was evaluated by measurement. The results are shown in Table 1 when the length is 2.0 μm or less, and when the length is more than 2.0 μm, it is defective.

(2) Heat resistance

After the pattern was finally formed, the color change (heat resistance) around 230 ° C / 2 hr was compared and evaluated. At this time, it was judged that the variation width of the calculated Eab was good, better than 1 and less than 3, good and more than 3 were poor, and the results are shown in Table 1.

Dimensional colorimetric system defined by L *, a *, b *. The smaller the color change value is, the more reliable the color filter can be manufactured.

[Equation 1]

? Eab * = (? L *) 2+ (? A *) 2+ (? B *) 2] 1/2)

(3) Chemical resistance

The chemical resistance was checked by observing the change in thickness when it was left in various chemicals (10% NaOH aqueous solution, 10% aqueous HCl solution, NMP). The thickness change ratio was calculated by the above-mentioned equation (1).

Similar to thermal tolerance, the better the exposure to chemicals is, the less the rate of change in thickness. When the change rate is 0.5% or less, excellent, 0.5% or less and less than 1% are good when immersed for 10 minutes at 40 ° C for each chemical substance at room temperature. And if it exceeds 1%, it is judged to be defective, and the results are shown in Table 1.
