[Object] To provide a laminate having inorganic nanoparticle-containing surface layer that exhibits a low gloss appearance and inorganic nanoparticle-containing radiation-curable ink. [Resolution Means] A laminate of an embodiment of the present disclosure has a substrate and a surface layer containing a cured product of a radiation-curable ink, the radiation-curable ink containing inorganic nanoparticles, a polyether-modified polymer, and at least one selected from the group consisting of a radiation-curable polymerizable oligomer and a radiation-curable polymerizable monomer, and the surface layer having a 60° surface glossiness of 50.0 GU or less.

Compositions and films are described comprising a polylactic (PLA) polymer and a copolymer comprising a first moiety comprising a C12-C30 alkyl group and a second moiety that is miscible in the composition. Suitable first moieties include a C12-C30 alkyl (meth)acrylate or a polyvinyl alcohol comprising pendent C12-C30 alkyl groups. Suitable second moieties include C1-C10 (meth)acrylic acid or ester thereof, vinyl acetate and ethylene vinyl acetate. The aforementioned composition may be used to form a release layer of an adhesive article such as a pressure sensitive adhesive tape. The films may be a monolithic film or a film layer of a multilayer film. The release layer may be disposed upon a substrate layer that may also comprise PLA. The films are produced by melt extrusion of the aforementioned composition and may be oriented.

Curable ink compositions include a curable aromatic monomer composition, and surface treated metal oxide nanoparticles. The surface treated metal oxide nanoparticles are surface treated with a mixture of at least two silane-functional surface treatment agents, at least one aromatic-containing silane-functional surface treatment agent and at least one silane-functional surface treatment agent comprising a co-polymerizable group. The curable ink composition is inkjet printable, having a viscosity of 30 centipoise or less at a temperature of from room temperature to 60&#xb0; C., and is free from solvents. The curable ink composition, when printed and cured, has a refractive index of 1.55 or greater, and is optically clear.

A method of making an adhesive article is described comprising melt extruding a core film layer comprising a composition comprising at least 50% of a polylactic acid polymer. The method further comprises melt extruding an adhesive layer on a major surface of the core film layer such that regions of interdiffusion are present between the core film layer and adhesive layer. The adhesive layer may comprise C1-C10 (meth)acrylic acid or ester thereof, vinyl acetate, ethylene vinyl acetate, hydrolysed polyvinyl alcohol and combinations thereof. The adhesive layer may also be a pressure sensitive adhesive. The method further comprises melt extruding a release film layer on an opposing major surface of the core film layer. The layers are sequentially extruded or co-extruded and can be uniaxially or biaxially oriented. Articles comprising a core film layer comprising a composition comprising at least 50% of a polylactic acid polymer and an adhesive layer disposed on a major surface of the core layer are also described.

A film is described comprising a first film layer having a Tg ranging from 30&#xb0; C. to 60&#xb0; C. The first film layer comprises a (meth)acrylic polymer and polyvinyl acetal polymer composition. The film further comprises a second layer proximate the first film layer. The second layer is different than the first film layer. The second may be a cured (meth)acrylic polymer film or coating; a backing such as thermoplastic polymer, woven or nonwoven fabrics, metal foils, paper, foams; or a coverfilm such as a fluoropolymer.
