Embodiment

[0164] Hereinafter, although this invention is demonstrated in detail based on an Example, this invention is not limited to an Example.

Synthetic example 1

[0165] Synthesis Example 1: Synthesis of Silane Compound B-1

[0166] In a reaction vessel equipped with a stirring device, a reflux condenser, a dropping funnel, and a thermometer, 100 parts by mass of isocyanatopropyltriethoxysilane (KBM9007, manufactured by Shin-Etsu Chemical Co., Ltd.) and 108 parts by mass of ureidopropyltrimethoxysilane (T1915, manufactured by Tokyo Chemical Industry Co., Ltd.) was added dropwise to a mixed solution of 485 parts by mass of N-methylpyrrolidone (NMP). Then, the temperature of the mixed liquid was raised to 65° C., and the reaction was carried out for 2 days while maintaining the temperature. At the end of the reaction, the disappearance of the isocyanate group peak was confirmed by IR.

[0167] The solid content concentration of the obtained solution was 30.0% by mass.

[0168] Through the above reaction, compound B-1 represented by the following formula was obtained. figure 1 It is an IR spectrum for confirming the completion of the re...

Synthetic example 2

[0170] Synthesis Example 2: Synthesis of Silane Compound B-2

[0171] In a reaction vessel equipped with a stirring device, a reflux condenser, a dropping funnel, and a thermometer, 100 parts by mass of isocyanatopropyltriethoxysilane (KBM9007, manufactured by Shin-Etsu Chemical Co., Ltd.) and 44 parts by mass of trimethylsilanol (LS-310, manufactured by Shin-Etsu Chemical Co., Ltd.) was added dropwise to a mixed solution of 336 parts by mass of N-methylpyrrolidone (NMP). Then, the temperature of the mixed solution was raised to 65° C., and the mixture was reacted for 2 hours while maintaining the temperature. The completion of the reaction is to confirm the disappearance of the isocyanate group peak by IR.

[0172] The solid content concentration of the obtained solution was 30% by mass.

[0173] Through the above reaction, compound B-2 represented by the following formula was obtained.

Abstract

Provided are: a photosensitive composition which exhibits sufficient adhesion to a base even in cases where film formation on the base is carried out at low temperatures; and a cured film of the photosensitive composition. A photosensitive composition according to the present invention contains (A) an acrylic resin, (B) a silane coupling agent and (C) a photopolymerizable compound. The silane coupling agent (B) is a silane compound that is a reaction product of a silicon compound represented by general formula (1) and having an isocyanate group and a silicon compound represented by general formula (2).

Description

technical field [0001] The present invention relates to a photosensitive composition, and more specifically, to a photosensitive composition suitable for use as an insulating film, retardation film, It is used as a panel material such as an optical characteristic film, and has excellent adhesion to the substrate even in low-temperature processing. Background technique [0002] In recent years, in the field of electronic and optical materials, improvement studies have been carried out on the following subjects: high definition, wide viewing angle, and high image quality of flat panel displays using liquid crystal or organic EL; Higher brightness, shorter wavelength, and whiter light sources of optical semiconductors such as light-emitting diodes (LEDs); higher frequency of electronic circuits; higher performance of optical and electronic components such as circuits and communications using light. In addition, in the technical field of semiconductors, reduction in size and we...
