Abstract:
A photocurable paint composition for road markings comprising:(A) 100 weight parts of a compound having an ethylenically unsaturated group, wherein said compound having an ethylenically unsaturated group does not comprise a monofunctional monomer having a boiling point less than 150.degree. C.,(B) 10 to 400 weight parts of a filler,(C) 30 to 400 weight parts of glass beads having a particle size of 0.01 to 10 mm,(D) 0.001 to 5 weight parts of a cationic dye represented by formula (1)D.sup.-.circle-solid.A.sub.1.sup.- (1)wherein D.sup.+ represents a cation having an absorption maximum wavelength in the wavelength region of from 400 to 1,200 mm, and A.sub.1.sup.- represents an anion,(E) 0.005 to 10 weight parts of a quaternary organic borate sensitizer represented by formula (2): ##STR26##wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each independently represents an alkyl group, an aryl group, an aralkyl group, an alkenyl group, an alkynyl group, a silyl group, a heterocyclic group or a halogen atom, and Z.sup.+ represents a cation, and(F) 0.01 to 10 weight parts of an ultraviolet radical polymerization initiator capable of generating a radical upon absorption of light at a wavelength of 400 nm or less.
