An asymmetrical dioxime ester compound and a manufacturing method for the same, and application

Japanese Patent JP6261778

B2

The present invention relates to an asymmetrical dioxime ester compound represented by general formula I and manufacturing method thereof. In general formula I, Ar1 is C6-C20 o-arylene or C3-C20 O-hetroarylene substituted by X1; Ar2 is C6-C20 arylene or C3-C20 hetroarylene, and is connected to Ar1 by X1; or when connected to Ar1 by X1, an ortho Ar2 carbon atom of the substituent group X1 thereof is connected to Ar1 by an axial bond, a carbon atom, carbonyl, O, S, or NR18 to form a ring structure; n is 0 or 1; X1 is NR18, O, or S, where C=O or S=O; Y1 is (CH2)mCR15R16, NR19, O(CR15R16)m, S(CR15R16)m, (CR15R16)m, where C=O and S=O; m is 0 or 1; R1, R2, and R3 are respectively a hydrogen atom, alkyl or alkoxy, alkyl or alkoxy and cycloalkyl substituted by any group, aryl and acyl substituted by any group. The present invention also relates to a photo-cured composition using the compound of general formula I as a photoinitiator, and the composition shows very high curing sensitivity when used for preparing a photo resistance device such as a display screen color filter.
