UV curable coating composition

摘要

The present invention is directed to a composition curable by radiation having a wavelength of 300 nm or more, a method of producing a coated substrate using such composition and the coated product so-produced. More particularly, the composition of the present invention comprises A) from about 1 to about 99% by weight of a specific aqueous polyurethane dispersion having a solids content of from about 20 to about 50% by weight, B) from about 1 to about 99% by weight of an aqueous polyester acrylate/urethane dispersion having a solids content of from about 20 to about 60% by weight, C) one or more photoinitiators, and D) water or a mixture of water and solvent
