ABSTRACT:
The object of the present invention is to find a resin composition for forming an ultraviolet absorbing layer having excellent adhesion to various plastic substrates such as polyester type films of PET etc. and provide a laminate of plastic substrate having no yellowing, excellent weather resistance and less curl formation with good productivity. There is provided a resin composition for use in forming an ultraviolet absorbing layer on the surface of a plastic substrate, having an ultraviolet absorbing polymer as a major component being synthesized from monomer mixtures containing an ultraviolet absorbing monomer, wherein the resin composition contains 0.5-5 parts by mass of a saturated polyester resin with a number-average molecular weight of 10000 or more and 0.1-30 parts by mass of a polyisocyanate based crosslinker relative to 100 parts by mass of the ultraviolet absorbing polymer, and a laminate with an ultraviolet absorbing layer made of the above composition formed on the surface of a plastic substrate.
