Embodiment

[0310] The following examples and comparative examples are given to further describe the present invention in detail, but the present invention is not limited to the following examples unless the gist is exceeded.

Synthetic example 1

[0311] [Synthesis example 1 (synthesis of epoxy acrylate resin having carboxyl group)]

[0312] In a 500mL four-necked flask, add 245g of bisphenol fluorene type epoxy resin (epoxy equivalent weight 245) represented by the following formula (a-1), 110mg of tetramethylammonium chloride, 100mg of 2,6-di-tert-butyl-4 -Methyl phenol, 72.0g of acrylic acid and 300g of propylene glycol monomethyl ether acetate are blown into the air at a speed of 25ml / minute, while heating and dissolving at 90°C to 100°C.

[0313] Next, the temperature was gradually raised while the solution was cloudy, and it was heated to 120° C. to completely dissolve it. Here, the solution gradually became transparent and viscous, and stirring was continued in this state. During this period, measure the acid value, continue heating and stirring until the acid value is less than 1.0 mg-KOH / g. It takes 12 hours for the acid value to reach the target value. Then cooled to room temperature to obtain bisphenol flu...

Synthetic example 2

[0318] [Synthesis example 2 (synthesis of epoxy acrylate resin having carboxyl group)]

[0319] Use 261g of bisphenol fluorene type epoxy resin (epoxy equivalent weight 261) represented by the following formula (a-2) instead of the bisphenol fluorene type epoxy resin represented by formula (a-1), except that it is the same as Synthesis Example 1 The synthesis was carried out to obtain a resin with an acid value of 103 mg-KOH / g and a molecular weight of 4400.

Abstract

The present invention discloses a highly sensitive photopolymerization initiator for a photopolymerizable composition which is used for the formation of a resin black matrix or the like. The photopolymerization initiator comprises an oxime ester compound represented by the general formula (I). (I) wherein R represents a hydrogen atom, an alkyl group, an alkenyl group, a heteroaryl group, or a heteroarylalkyl group, or R may, together with X or Y, form a ring; R represents an alkanoyl group, an alkenoyl group, a cycloalkanoyl group, an aryloyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a heteroaryl group, a heteroaryloyl group, or an alkylaminocarbonyl group; X represents a bivalent aromatic hydrocarbon group and / or aromatic hetero group which is produced by the fusion of two or more rings; and Y represents a fused ring group having one or more rings fused to a phenyl group or a univalent group derived from a monocyclic aromatic heterocyclic ring.

Description

technical field [0001] The present invention relates to an oxime ester compound useful as a photopolymerization initiator, a photopolymerization initiator containing the oxime ester compound, and uses thereof. [0002] The photopolymerizable composition containing the photopolymerization initiator of the present invention is useful for the manufacture of optical color filters used in, for example, color televisions, liquid crystal display elements, solid-state imaging elements, cameras, etc. optical filter. Since the photopolymerizable composition containing the photopolymerization initiator of the present invention has particularly high sensitivity and excellent resolution, it is possible to produce a high-definition and high light-shielding black matrix (Black Matrix; hereinafter sometimes abbreviated as "BM"). By using such a photopolymerizable composition, a high-definition and high-quality color filter and a liquid crystal display device can be realizable. [0003] The ...
