Process for preparing decorative surface appearance in acrylic material employing anisotropic particles

摘要

A decorative surface appearance in an acrylic material is obtained by applying a flowable crosslinkable acrylic material containing anisotropic particles having an aspect ratio of 3 to a shrinkable support followed by crosslinking to form a solid article.

1. A process for preparing a decorative surface appearance in a decorative acrylic material comprising the steps of
(a) forming a liquid composition containing a crosslinkable acrylic material and anisotropic particles with a majority of the anisotropic particles having an aspect ratio of at least three, (b) applying the liquid composition to a shrinkable support, (c) solidifying the liquid composition by crosslinking while allowing the support to shrink, to form a solid article wherein the difference between the shrinkage of the support compared to the shrinkage of liquid composition is at least 0.1%.
