Copolymers prepared by the free-radical copolymerization of the following components: a) cationic monomers selected from the group consisting of cationic (meth)acrylamide monomers and diallyldimethylammonium chloride, b) polyethylene glycol macromonomers, and c) uncharged acrylamide monomers.

A thermoset resin for forming parts to be metal plated includes a vat photopolymerization (VPP) thermoset resin and an etchable phase disposed in the VPP thermoset resin. The etchable phase is etched from a surface of a part formed from the VPP thermoset resin such that a plurality of micro-mechanical locking sites is formed on the surface of the part. The etchable phase is at least one of organic particles, organic resins, inorganic particles, and copolymers of the VPP thermoset resin. For example, the etchable phase can be a polybutadiene phase and/or a mineral such as calcium carbonate.

Provided herein are curable compositions for use in a high temperature lithography-based photopolymerization process, a method of producing crosslinked polymers using said curable compositions, crosslinked polymers thus produced, and orthodontic appliances comprising the crosslinked polymers.

Adhesives, particularly reversible adhesives, reversible adhesive hydrogel meshes and polymer formulations that may be used in preparation of the reversible adhesive hydrogel meshes are disclosed. The polymer formulations may comprise a reversible monomer of a reversible adhesive polymer, acrylic acid (AA), an acrylate cross-linker, a photo-initiator for free radical polymerization, and a solvent. The disclosure also relates to a wound dressing comprising the reversible adhesive hydrogel meshes. Such wound dressings are particularly suitable for treatment of damaged sensitive tissue, for example, wounds formed on a fragile skin.

A photocurable silicone composition is disclosed. A cured product of the composition is also disclosed. The photocurable silicone composition comprises: (A) an organopolysiloxane having at least one aryl group with 6 to 12 carbons and at least one alkenyl group with 2 to 12 carbons in a molecule; (B) an organic compound having at least two ether bonds and at least one aliphatic carbon-carbon double bond in a molecule; (C) a thiol group-containing organic compound comprising; (C.sub.1) an organic compound having two thiol groups in a molecule, and (C.sub.2) an organic compound having at least three thiol groups in a molecule; and (D) a photoradical initiator. The composition generally suppresses crack and delamination of a cured product laminated between two substrates after thermal aging.

A composition set containing: a first liquid containing an oxidizing agent; and a second liquid containing a reducing agent, wherein at least one of the first liquid and the second liquid contains a compound represented by the following formula (1):

##STR00001##

wherein R.sup.11 and R.sup.12 each independently represent a hydrogen atom or a methyl group, and R.sup.13 represents a divalent group having a polyoxyalkylene chain, and wherein the polyoxyalkylene chain has 100 or more of oxyalkylene groups.

A stretchable film is made of, at least as a top surface of the stretchable film, a cured product of a stretchable film material containing a silicone polyurethane resin. The top surface of the stretchable film has a repeated uneven pattern formed with depths of 0.1 μm to 2 mm and pitches of 0.1 μm to 5 mm. Thus, the present invention provides a stretchable film having excellent stretchability, with the film top surface being excellent in water repellency and free from sticking; and a method for forming the stretchable film.
