Abstract: The present disclosure provides laminates, which include adhesive materials and methods that allow for the removal of contaminants, e.g. particulate contaminants, from a substrate surface. In one embodiment, the laminates include (i) a substrate with contaminant disposed on its surface, (ii) a liquid, adhesive precursor and (iii) a film layer. The liquid, adhesive precursor is disposed between the substrate and the film layer. In another embodiment, the laminates include (i) a substrate with contaminant disposed on its surface, (ii) a cured adhesive layer and (iii) a film layer. The cured adhesive layer is disposed between the substrate and the film layer. The laminates may be used to remove contaminant from the substrate surface by removal of the film layer and the cured adhesive layer, which entraps the contaminant therein.

Abstract: The present disclosure provides a photopolymerizable composition. The photopolymerizable composition includes a) 40-60 parts by weight of a monofunctional (meth)acrylate monomer, per 100 parts of the total photopolymerizable composition; b) a photoinitiator; and c) a polymerization reaction product of components. A cured homopolymer of the monofunctional (meth)acrylate monomer has a glass transition temperature of 125 degrees Celsius or greater. The polymerization reaction product of components includes i) a diisocyanate; ii) a hydroxy functional methacrylate; iii) a polycarbonate diol; and iv) a catalyst. The polymerization reaction product includes a polyurethane methacrylate polymer. Often, the polyurethane methacrylate polymer has a weight average molecular weight of 8,000 g/mol or greater. The present disclosure further provides an article and methods thereof.

Abstract: The present disclosure provides a retroreflective article. The retroreflective article includes a retroreflective layer including a number of cube corner elements that collectively form a structured surface that is opposite a major surface, and a conformal wavelength-selective radiation absorbing coating layer adjacent to the structured surface. The present disclosure also provides a method of making a retroreflective article. The method includes obtaining a retroreflective layer, and forming a conformal wavelength-selective radiation absorbing coating layer on the retroreflective layer by applying a first material having a first binding group to the structured surface, and applying a second material having a second binding group to the first material. The conformal wavelength-selective radiation absorbing coating layer absorbs radiation of at least one selected wavelength and can impart color (or absorption of at least one wavelength outside of the colored wavelength range) to retroreflective light of the retroreflective article.

Abstract: A method of making a shaped abrasion-resistant multilayer optical film includes providing a curable composition comprising, based on the total weight of components a) to d) components: a) 87 to 96 weight percent of urethane (meth)acrylate compound having an average (meth)acrylate functionality of 2 to 4.8; b) 2 to 12.5 weight percent of (meth)acrylate monomer having a (meth)acrylate functionality of 1 to 2, wherein the (meth)acrylate monomer does not comprise a urethane (meth)acrylate compound; optionally c) 0.5 to 2 weight percent of silicone (meth)acrylate; and d) optional effective amount of photoinitiator. The curable composition is coated onto an MOF. Optionally, the curable composition to is at least partially dried. Next, the curable composition or the at least partially dried curable composition is at least partially cured to provide an abrasion-resistant multilayer optical film. Lastly, the abrasion-resistant multilayer optical film is thermoformed using a female mold having a mold surface. At least a portion of the mold surface has a radius of curvature of 58 to 76 mm and a maximum depth of 13 to 20 mm.
