Abstract: A coated substrate comprising a coating extending over at least a part of the substrate. The coating is obtainable from a coating composition comprising (a) a polymeric binder; and (b) a feathering reducing agent comprising a carboxylic acid reactive functional group. The coated portion of the substrate comprises a pretreatment layer. The pretreatment layer is obtainable from a pretreatment composition that comprises a trivalent chromium compound. The invention extends to a method of coating a pre-treated substrate and a coated package, such as a metal can.

Abstract: A coating composition comprising (a) a polyester binder material; and (b) a feathering reducing agent. The feathering reducing agent is selected from (i) an acrylic feathering reducing agent comprising a functional group selected from hydroxyl, epoxide, phosphatized epoxide and/or acid-functional; (ii) a hydroxy-functional polyester feathering reducing agent; (iii) a feathering reducing agent comprising a functional group selected from amine, amide, imine and/or nitrile; (iv) a phosphatized epoxy feathering reducing agent; (v) a phenolic resin feathering reducing agent; and/or (vi) a feathering reducing agent comprising an oxazolyl functional group. The invention extends to a substrate coated with the coating composition and use of the coating composition to reduce feathering.

Abstract: The present invention relates to a coating composition, the coating composition comprising: a) a solution polymerised acrylic material; b) an emulsion polymerised acrylic latex material, wherein one or both of the solution polymerised acrylic material and the emulsion polymerised acrylic latex material have acid functionality; and c) a crosslinker material operable to crosslink the acid functionality on the solution polymerised acrylic material and/or emulsion polymerised acrylic latex material, the present invention also extends to a food and/or beverage package coated on at least a portion thereof with said coating composition.

Abstract: A polyhydroxyalkylamide material having the formula (I), wherein Z represents a polymer or an alkylene, alkenylene, alkynylene or arylene group; Z? represents a bivalent organic linking group; m is 0 or 1; X represents a bivalent organic bridging group; R represents a hydroxyalkylamide group; and n is at least 2. The present invention extends to coatings compositions containing the polyhydroxyalkylamide material and articles coated with coatings derived from said coated compositions.

Abstract: There is described a method for the production of a functional polyester having functional group X. The method comprises the step of melt blending a composition comprising (i) a high number average molecular weight (Mn) polyester having a Mn of ?6,000 Da; and (ii) a functional compound comprising functional group Y which may be the same as functional group X or be different to functional group X but be operable to form functional group X in the functional polyester. The composition is melt blended such that the high Mn polyester and the functional compound react to produce the functional polyester. The high Mn polyester has a Mn that is higher than the Mn of the functional compound. The present invention extends to functional polyesters produced by the method; aqueous, solventborne and powder coating compositions containing the functional polyester, and articles coated with the said coating compositions.

Abstract: The present invention relates to a coating composition, the coating composition comprising: a) a solution polymerised acrylic material; b) an emulsion polymerised acrylic latex material, wherein one or both of the solution polymerised acrylic material and the emulsion polymerised acrylic latex material have acid functionality; and c) a crosslinker material operable to crosslink the acid functionality on the solution polymerised acrylic material and/or emulsion polymerised acrylic latex material, the present invention also extends to a food and/or beverage package coated on at least a portion thereof with said coating composition.
