PROBLEM TO BE SOLVED: To provide a synthetic resin laminated material which is a synthetic resin molding having such coating as excellent in transparency, scratch resistance, solvent resistance and antistatic performance, and its producing method, and a photocuring resin composition and its cured material used as a raw material for the coating. SOLUTION: In the synthetic resin laminated material wherein a crosslinking polymer coating is formed on at least a part of a surface of the synthetic resin molding, a lithium salt of 1.7 to 9.1% is included of which the coating is expressed as R<1> -SO3 Li (R<1> expresses an alkyl group or an 8-20C alkylphenyl group). The photocuring resin composition includes a mixture of 10 parts composed of a monomer of 50 to 100% having at least two acryloyloxy groups and/or methacryloyloxy group in a molecule and a monomer of 0 to 50% having oneα-,β-ethylene family unsaturated linkage in a molecule, the lithium salt of 2 to 10 parts and a photo-initiator of 0.1 to 10 parts. The cured material includes the composition.
