Photodeformable article having photoionizable groups on a polymer backbone

Abstract

Abstract The invention is directed to polymeric materials which undergo deformation upon exposure to actinic radiation. These polymeric materials contain at least one photoionizable group attached to a polymer backbone structure. Typically, photoionizable groups can include N,N-dimethyl-p-phenylenediamine, tetrathiafulvalene, tetraselenafulvalene, ferrocene, tetrathiatetracene and leuco dyes such as leuco methyl violet. Polymer backbone structures which can be used can be chosen from polyacrylics, polyglutamate, polyvinyl amine, polyvinyl alcohol, polystyrene and the like. Films of these materials when exposed to actinic radiation display deformations with dilations of about 35% in each dimension. They are useful for forming relief images for printing, three dimensional photography, photocopy, holographic information storage, information storage and actinometry.
