Photocurable paint composition for road markings

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° 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−[Circlesolid]A1− (1)
• wherein D+ represents a cation having an absorption maximum wavelength in the wavelength region of from 400 to 1,200 mm, and A1− represents an anion,
• (E) 0.005 to 10 weight parts of a quaternary organic borate sensitizer represented by formula (2):
• wherein R1, R2, R3 and R4 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+ 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.
