PHOTOPOLYMERIZABLE COMPOSITION

摘要

PURPOSE:To obtain the title composition designating the maximum sensitivity within the range of ultraviolet light and visible light and having excellent photopolymerization speed containing addition polymerizable compound having one or more ethylenically unsaturated double bonds and photopolymerization initiator as essential components. CONSTITUTION:To (A) addition polymerizable compound having one or more ethylenically unsaturated double bonds, (a) 2-pyrazoline derivative of the formula [R<1-3> is same or different of (substed.) alkyl, (substed.) aryl or (substd.) 1- alkenyl] and (b) a compound having one or more oxo oxygen atom bound to aromatic ring or a compound having one or more oxo oxygen bound with C of aromatic ring through C atom are compounded at the wt. ratio of about 30:1- about 1:30 to prepare a photopolymerization initiator (B) and about 0.1-20wt% of the photopolymerization initiator is compounded with organic high molecular substance (C) having the compatibility with A and B and coating forming property as a binder.
