A microstructure-bearing composite plastic article can be superior, both in microstructure and in physical properties, when it is a composite of a tough, flexible substrate, at a surface of which is microstructure formed of a cured oligomeric resin having hard segments and soft segments, which cured resin is substantially confined to the microstructure portion of the composite. Such a composite plastic article can be made by depositing an uncured oligomeric resin composition onto a master negative molding surface in an amount barely sufficient to fill the cavities of the master, filling the cavities by moving a bead of the composition between a substrate and the master, and curing the deposited composition by ultraviolet radiation while keeping the temperature during curing to not more than 50°C. above the typical use temperature of the finished composite plastic article.
A composite plastic article comprising a tough, flexible substrate, one face of which bears a microstructure of utilitarian discontinuites, which discontinuities have a depth of at least 0.025 mm to about 0.5 mm, said microstructure comprising a layer of a cured oligomeric resin having hard segments
A composite plastic article comprising a tough, flexible substrate, one face of which bears a microstructure of utilitarian discontinuites, which discontinuities have a depth of at least 0.025 mm to about 0.5 mm, said microstructure comprising a layer of a cured oligomeric resin having hard segments and soft segments, wherein the total thickness of the layer of cured resin is not more than 20% greater than the depth of the discontinuities.
