Example Embodiment

[0309] Example

[0310] Examples and comparative examples are given below to further describe the present invention in detail, but as long as the gist of the present invention is not exceeded, the present invention is not limited to the following examples.

Example Embodiment

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

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

[0313] Next, keep the solution turbid and slowly raise the temperature, and heat 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, the acid value is measured, and heating and stirring are continued 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 it is cooled to room temperature to obtain bisphenol fluorene type epoxy ac...

Example Embodiment

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

[0319] The same as Synthesis Example 1 except that 261 g of the bisphenol fluorene type epoxy resin represented by the following formula (a-2) (epoxy equivalent 261) was used instead of the bisphenol fluorene type epoxy resin represented by the formula (a-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 ...
