<p>PURPOSE:To improve developability, photosensitivity, adhesive properties, electrical insulating properties, resistance to electrolytic corrosion, etc., by compounding a specific photosensitive prepolymer, a diluent, a photopolymn. initiator, and a photopolymn. accelerator. CONSTITUTION:21-84wt.% photosensitive prepolymer having at least two ethylenically unsatd. bonds in the molecule, 11-78wt.% diluent comprising a photopolymerizable vinyl monomer and/or an org. solvent, 0.5-25wt.% compd. of formula I (where R1, R2, and R3 are each H, Cl, Br, F, 1-5C alkyl, or 1-5C alkoxy excluding when they all are H) as the photopolymn, initiator, and 0.05-25wt.% compd. of formula II (wherein R4 an R5 are each 1-3C alkyl; R6 is -OR7,-OCH2CH2CH2OR7, H, 1-13C alkyl, phenyl, or a group of formula III; and R7 is 1-13C alkyl) as the photopolymn. accelerator are compounded.</p> |
