The present invention relates to a siloxane hard resin including alicyclic epoxy siloxane alone or a reactive monomer, which is prepared by condensation reaction of alkoxysilanes, and has a weight average molecular weight in the range of 1000 to 4000 and a molecular weight distribution of PDI 1.05 to 1.4. A siloxane hard cured article produced by photo- or thermal polymerization has high hardness by compact crosslinking of siloxane molecules having different molecular weights.

A laminated adhesive tape includes a substrate comprising two or more plies of thin, flexible material, the substrate having a first major surface and a second major surface opposite the first major surface. A polymeric laminating composition comprising a polymer and an alkyl ketene dimer binds the two or more plies and a pressure sensitive adhesive carried on the first major surface. In a further aspect, a method of making a laminated adhesive tape is provided.

The present invention provides a cationic photocurable composition, a paint, an article of manufacture with photocured coating, and an ink. The cationic photocurable composition comprises A1; and/or A2; B: an epoxy compound; and C: a cationic initiator. On this basis, in one aspect, when the cationic photocurable composition of the present invention is subsequently used as a paint, the wet adhesion between the coating formed of the paint to a substrate film interface is better, and the coating also has excellent abrasion resistance. In another aspect, when subsequently used as an ink in intaglio printing, the described cationic photocurable composition can also more effectively avoid the occurrence of plate fogging.
