A crosslinking polyvinyl acetate (XPVAc or X-PVAc) adhesive is applied as a primer (i.e., a basecoat) or an exterior coat (i.e., a top coat) on a wood preservation product which is mainly treated with a water-based preservative. By sealing the exterior wood surfaces, the new coating system not only effectively prevents the leaching of the preservative by bonding and chelating with the unfixed preservative compounds or complexes at the surface layer, but it also significantly reduces surface aging of wood, maintains effective preservation functions, and provides a longer service life to the wood preservation product. 1.

PHOTOCURABLE RESIN COMPOSITION, INK AND COATING MATERIAL

Номер: US20190135955A1

Принадлежит:

Provided is a photocurable resin composition containing an allylic polymer (A) which has excellent adhesion to plastic substrates. The present invention relates to a photocurable resin composition containing an allylic polymer (A), the allylic polymer (A) being produced by polymerization of an allylic compound represented by the following formula (I): 17-. (canceled)10. The method according to claim 8 , wherein the photocurable resin composition further comprises an ethylenically unsaturated compound (B).11. The method according to claim 8 , wherein the photocurable resin composition further comprises a photopolymerization initiator. The present invention relates to a photocurable resin composition containing an allylic polymer (A) and also relates to an ink and a coating material including the resin composition. Specifically, the present invention relates to a photocurable resin composition having excellent adhesion to plastic substrates.Various resin compositions that can be cured by light (e.g. ultraviolet rays) have been used in inks, coating materials, adhesives, photoresists, and other applications. For example, UV curable printing inks are highly valued because, e.g., they have a high cure rate so that they can be cured in a short time;they are environmentally friendly due to no use of solvents; and they can save resources and energy. Therefore, they are increasingly widely used in practice.Among such resin compositions, those containing diallyl phthalate resins derived from diallyl phthalate (diallyl orthophthalate, diallyl isophthalate, or diallyl terephthalate) are used as UV offset inks for paper.However, in offset ink applications, the incorporation of diallyl phthalate resins is known to result in insufficient adhesion to plastic substrates (see, for example, Patent Literature 1). Moreover, Patent Literature 2 describes an active energy ray-curable resin composition that contains a diallyl hydrogenated phthalate prepolymer with an alkyl group on the ...
