Radiation curable compositions containing outstanding reactive diluents have been developed. The diluents are lower alkyl ether acrylates and methacrylates of particular alkoxylated and non-alkoxylated polyols. Examples are mono-methoxy trimethylolpropane diacrylate, mono-methoxy neopentyl glycol monoacrylate and mono-methoxy, ethoxylated neopentyl glycol monoacrylate having an average of about two moles of ethylene oxide.

Pressure sensitive recording sheets are prepared characterized by containing on one side thereof color former dissolved in a solvent which is one or a mixture of alkoxy diphenyl alkanes having the following structure: ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are H or a straight or branched chain alkyl group of 1 to 8 carbon atoms and can be the same or different; R.sub.5 is a straight or branched chain alkyl group of 1 to 9 carbon atoms; R.sub.6 is a straight or branched chain alkyl group of 1 to 8 carbon atoms; x is 0, 1 or 2; y is 1 or 2 and n is 1 or 2, with the proviso that the sum of the carbon atoms in R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 does not exceed 9 and with the further proviso that where the alkoxy diphenyl alkane is a solid to viscous liquid, at least one diluent or at least one other generally liquid solvent or mixture thereof is present. The treated side of the sheet is brought into contact with a developer. Upon application of pressure, color is produced by reaction between the color former and the developer.
