A polyol polymer is obtained from reactants including: a) a non-aromatic epoxy functional compound that includes at least 30 weight % of the total solids weight of the reactants; and b) an aromatic mono-carboxylic acid functional compound, or anhydride thereof, that is substantially free of non-aromatic ethylenic unsaturation. The polyol polymer has ester linkages and hydroxyl functional groups. Further, if the reactants further include an aromatic polycarboxylic acid, the aromatic polycarboxylic acid makes up less than 15 weight % of the total solids weight of the reactants. A coating composition is also prepared with the polyol polymer.

Polyol polymers, methods of preparing such polymers, and coating compositions containing the same

The present invention relates to polymers that include residues of at least one monomer represented by the following Formula (I). With reference to Formula (I), at least one of E1 and E2 independently is, or is independently substituted with, at least one reactive group, such as a (meth)acryloyl group. Monomers represented by Formula (I) and monomer residues thereof have alignment properties, such as photoalignment properties. The present invention also relates to alignment layers that include such polymers, and articles of manufacture, such as optical elements, that include one or more such alignment layers. 

Alignment polymers

A silicone-containing polyester polyol can include a reaction product prepared from reactants including: a diol; a polyol having at least three hydroxyl groups; a dimer of a fatty acid having two carboxylic acid groups, or an anhydride or ester thereof; and a silicone component having siloxane linkages and at least two reactive functional groups selected from hydroxyl groups, amino groups, thiol groups, carboxylic acid groups, anhydride groups, or combinations thereof. A coating composition for preparing an anti-fingerprinting, soft touch coating can include the silicone-containing polyester polyol and a crosslinker reactive with the silicone-containing polyester polyol.

Silicone-containing polyesters, coating compositions containing the same, and coatings formed therefrom

The present invention relates to compounds represented by the following Formula (I). With reference to Formula (I), at least one of Eand Eindependently is, or is independently substituted with, at least one reactive group, such as a (meth)acryloyl group. The compounds of the present invention can be used alone and/or in combination with polymers prepared from such compounds, such as to form or as one or more components of an alignment layer. 

Alignment compounds

The present disclosure provides for new photoalignment (co)polymer materials which demonstrate improved adhesion to a substrate. The (co)polymeric structure includes at least one photochemically active chromophore and at least one adhesion promoter group. Articles of manufacture, optical elements, ophthalmic elements and liquid crystal cells which include at least one photoalignment layer made from the photoalignment (co)polymer materials and methods for formation are also disclosed.

Photoalignment materials having improved adhesion

A stain resistant coating composition can include: (a) a polyester polyol; (b) a silicone component having at least one reactive functional group; and (c) a crosslinker reactive with (a) and (b). The polyester polyol can include a reaction product obtained from a mixture of reactants including: an aliphatic diol; a polyol having 3 or more hydroxyl groups; and an aliphatic cyclic polycarboxylic acid, or an anhydride or ester thereof, that is greater than 10 mole % of the total carboxylic acids, or anhydrides or esters thereof, used to prepare the polyester.

Stain resistant coating compositions and coatings formed therefrom

A stain resistant, soft touch coating composition can include: (a) a fluoropolymer comprising at least one reactive functional group; (b) a polyester polyol; and (c) a crosslinker reactive with (a) and (b). The polyester polyol can include a reaction product obtained from a mixture of reactants including: an aliphatic diol; a polyol having 3 or more hydroxyl groups; and a cyclic polycarboxylic acid, or an anhydride or ester thereof.
