The present invention is drawn to low migration energy-curable compositions comprising epoxy acrylates derived from the reaction of poly(alkylene oxide) containing glycidyl ethers with acrylic acid. The compositions of the invention are particularly useful for the printing or coating of food packaging.

A curing agent and method for producing the same are provided, the method includes: esterification reaction: reacting a polyhydric alcohol with a polybasic acid anhydride to obtain an ester-based emulsifier (A); chain extension reaction: reacting an ester-based emulsifier (A) with a bifunctional epoxy resin to obtain a polymer intermediate (B); and reacting the polymer intermediate (B) with a polyamine compound to obtain a curing agent (C).

The invention relates to the use of a polymer for improving the clean-ability of a surface coating or for reducing the dirt pick up of a surface coating, wherein the polymer is a a non-crosslinked polymer having a polymer main chain comprising i) polysiloxane segments comprising repeating units of the formula (I) wherein R 1 independent of each occurrence represents a hydrocarbyl group and n is an integer in the range of 6 to 150, and ii) non-polysiloxane segments having at least one functional group comprising at least one of hydroxyl group, acryloyl group, methacryloyl group, acetyl group, urethane group, and methyl ether group, wherein the number of links between non-polysiloxane segments and polysiloxane segments in the polymer is less than 9.5%, calculated on the average number of silicon atoms per polysiloxane segment, and wherein at least one non-polysiloxane segment is located between two polysiloxane segments.
