Patent ID: 8088552

Claim:
A photosensitive composition comprising: an alkali soluble resin having a monomer unit represented by the following formula (I): wherein, in the formula (I), R 1 represents a hydrogen atom or a C 1-10 alkyl group which may have a substituent, and L represents an alkylene group which may have a substituent or an arylene group which may have a substituent; a silane coupling agent represented by the following formula (II): wherein, R 2 to R 4 each represents a hydrogen atom, an alkyl group which may have a substituent, or an alkoxy group, X represents an ester bond, an amide bond, or a phenylene group, Z stands for 0 or 1, and Y stands for an integer from 1 to 10; an infrared absorber; a radical polymerization initiator; and a polymerizable compound having an ethylenic double bond, wherein the silane coupling agent is contained in an amount ranging from 15% to 40% of the photosensitive composition by mass, wherein the alkali soluble resin has further a monomer unit represented by the following formula (III) and/or (IV): wherein, in the formulas (III) and (IV), R 1 represents a hydrogen atom or a C 1-10 alkyl group which may have a substituent, and M represents a C 1-10 alkylene group which may have a substituent.
