Abstract
A blend activatable with actinic radiation and solid at room temperature, comprising (A) at least one crystalline compound containing on average per molecule at least one reactive functional group having at least one bond which can be activated with actinic radiation, and (B) at least one amorphous compound containing on average per molecule at least one reactive functional group having at least one bond which can be activated with actinic radiation; process for its preparation, and its use.
Claims2
A process for preparing a blend with the aid of a multistage process, comprising one of
- (I) in a first variant, in at least one first stage, preparing at least one compound (B) and then, in at least one second stage, preparing at least one compound (A) in the at least one compound (B) as reaction medium, or
- (II) in a second variant, in at least one first stage, preparing at least one compound (A), and then preparing, in at least one second stage, at least one compound (B) in the at least one compound (A) as reaction medium, wherein the blend is activatable with actinic radiation and is solid at room temperature and comprises
- (A) at least one crystalline compound containing on average per molecule at least one reactive functional group having at least one bond which can be activated with actinic radiation, and
- (B) at least one amorphous compound containing on average per molecule at least one reactive functional group having at least one bond which can be activated with actinic radiation.
