Abstract:
A radiation curable coating, adhesive, or photoresist ink composition comprising (A) at least one oil soluble polymerizable, ethylenically unsaturated compound of formula whereinM is one or more metal atoms of valence n, wherein n=y w, wherein M is optionally more than one metal atom, with the proviso that the global equivalent metal valence is n=w y; n is an integer of about 1-6; R is a residue of a compound having anhydride and/or carboxylic acid groups with an initial equivalent carboxy equivalent functionality defined by the equation f=x+y+z, wherein f is an integer of about 2 to 30; R1 is a residue of a hydroxy-containing ethylenically unsaturated compound; R2 is hydrogen or a residue of a hydroxy-containing ethylenically unsaturated compound different from R1 or another metal group M; R3 is a residue of a hydroxy-containing ethylenically unsaturated compound; w is a number of moieties having residue R required for metal valence n; x is an integer of about 1 fâˆ’1; y is an integer of about 1 to 2; z is an integer of about 0 to fâˆ’2; Y is hydrogen or R3; (B) at least one copolymerizable ethylenically unsaturated monomer or oligomer; and (C) at least one unimolecular or bimolecular photoinitiator; said composition being substantially free of peroxide initiator.
