The present disclosure provides a photopolymerizable composition. The photopolymerizable composition includes at least one urethane component, at least one monofunctional reactive diluent, an initiator, and optionally an inhibitor. The present disclosure also provides an article including the reaction product of the photopolymerizable composition. Further, the present disclosure provides a method of making an article. The method includes (i) providing a photopolymerizable composition and (ii) selectively curing the photopolymerizable composition to form an article. The method optionally also includes (iii) curing unpolymerized urethane component and/or reactive diluent remaining after step (ii). Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.

Described in preferred embodiments are UV curable coating compositions including a unique blend of aliphatic urethane acrylate resins. Also described are coated articles and methods for their production involving the use of the coating compositions.

Provided are a curable composition including, a block copolymer including a block A which has a constitutional unit having an ethylenically unsaturated group in a side chain of a polymer compound, a pigment, and, a photopolymerization initiator, in which a content of a polymerizable compound is 15 mass % or less with respect to a total solid content of the curable composition; a cured product of the curable composition; a color filter including the cured product; and a solid-state imaging element or an image display device including the color filter.

The present invention relates to a specific radiation-curable coating composition for improving the surface adhesion of plastic parts and its uses as a primer coat, as a base coat or as a clear coat. The composition may be pigmented or unpigmented and may be cured by UV and/or EB. The invention also relates to cured coating resulting from this cure and to the coated plastic substrate with improved surface adhesion.

The present invention provides a curable resin composition containing a polyester resin (A) having a (meth)acryloyl group and a monofunctional (meth)acrylate compound (B1) and/or a difunctional (meth)acrylate compound (B2). The average functional group number of (meth)acryloyl groups possessed by the polyester resin (A) is within a range of 1.5 or more and 3 or less, and the content of the polyester resin (A) in the curable resin composition is 50% by mass or more. The curable resin composition has low viscosity and produces a cured product having excellent mechanical properties, and thus can be preferably used as a resin composition for optical three-dimensional shaping.

There is described an acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component, with (ii) a polyol component, including—2,2,4,4-tetraallcylcyclobutane-1,3-diol. One of the polyacid component or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. Also provided is an aqueous coating composition comprising the acrylic polyester resin and a metal packaging containing coated with the composition.

Corrosion resistance coatings and dicyclopentadiene modified ester oligomers useful in corrosion resistant coatings. The corrosion resistant coatings exhibit improved corrosion resistance, improved adhesion, lower toxicity, unlimited pot life, and/or lower volatile organic compounds (VOCs).
