The invention relates to a radiation curable composition comprising relative to the total weight of the composition (A) 0&#x2013;29 wt % of a cationically curable component having a linking aliphatic ester group, (B) 10&#x2013;85 wt % of an epoxygroup containing component other than A, (C) 1&#x2013;50 wt % of an oxetanegroup containing component, (D) 1&#x2013;25 wt % of a multifunctional acrylate and a radical photoinitiator and a cationic photoinitiator.

Radiation curable resin composition and rapid prototyping process using the same

The invention relates to a radiation curable composition comprising radiation curable components wherein at least one component of the radiation curable composition contains a functional group which, when attached to an acrylate group has a calculated Boltzmann average dipole moment of higher than 3.5 Debye. The invention further relates to radiation curable optical fiber coating compositions having a high dielectric constant.

Radiation curable compositions

The invention relates to a radiation curable powder paint binder composition comprising a radiation curable compound being a mono or multi valent carboxylic ester of a &bgr;, &ggr;, &dgr;, or &egr;-hydroxyalkylamide group containing compound, in which the carboxylic ester is derived from an &agr;, &bgr;-ethylenically unsaturated carboxylic acid.

Powder paint binder composition

Radiation-curable compound derived from a hydroxyalkylamide

The invention relates to a radiation curable composition comprising a mono or mulit valent carboxylic ester of a &bgr;-hydroxyalkylamide group containing compound, in which the carboxylic ester is derived from an &agr;,&bgr;-ethylenically unsaturated carboxylic acid. A coating composition based on this composition has a high rate of polymerisation and shows the desired chemical and mechanical properties.
