Publication number: 20120099412Abstract: An ultraviolet curable composition having, a coating film cured with ultraviolet rays with a large number of crosslinking points due to a (meth)acrylate compound that does not intramolecularly have a cyclic moiety and has a functionality of three or more and, the compound does not intramolecularly have a cyclic moiety, plastic deformation due to a cyclic moiety is less likely to occur. Additionally, a monofunctional (meth)acrylate compound forms a homopolymer having a glass transition temperature of 20° C. or less, has a low glass transition temperature, and is flexible. Curing contraction caused in ultraviolet curing is suppressed and plastic deformation is less likely in the resultant cured film at room temperature.

Publication number: 20100278031Abstract: With branched epoxy(meth)acrylate which comprises a phenyl skeleton serving as a stiff molecular skeleton, and which comprises in the molecular skeleton a number of branched structures capable of forming a coating structure at a high crosslinking density after ultraviolet curing, it becomes possible to design the coating hardness to be high even if the content of an acryloyl group is designed to be low to effect less crosslinking reaction induced by ultraviolet curing, and it becomes possible to relax distortions inside a cured film due to cure shrinkage which occurs at the time of ultraviolet curing. As a result, there can be realized an ultraviolet-curable composition for an optical disk which has a high elastic modulus and is less tilted at the time of curing even if the coating hardness is designed to be high.Type: ApplicationFiled: October 28, 2008Publication date: November 4, 2010Inventors: Junji Yamaguchi, Daisuke Ito, Youichi Tanimoto, Hiroyuki Tokuda, Yasunari Kawashima, Hiroyuki Terada
