    摘要: The invention relates to stabilized photopolymerizable or photocrosslinkable polymeric compositions having improved storage stability. These compositions are useful as coating and moldable compositions which are hardenable by ultraviolet radiation. These coating and moldable compositions comprise mixtures of photopolymerizable or photocrosslinkable unsaturated compounds, at least one photoinitiator and a particular nitrone.

    摘要: The present invention provides a novel linear amorphous aromatic polyester comprising units derived from (i) terephthalic acid, (ii) 1,2-propanediol or mixtures of 1,2-propanediol with up to 20 mole percent of ethylene glycol, based upon the total of 1,2-propanediol and ethylene glycol, and (iii) about 5 to 30 mole percent, based upon the total of (i), (ii), and (iii), of a glycol which contains a tertiary amine group, the amine containing glycol having a specified structure and the polyester having an inherent viscosity of about 0.05 to 0.5 dl/g when measured in 60:40 phenol:tetrachloroethane at a concentration of 0.5 g/100 ml at 25.degree. C. The novel polyester is useful as a crosslinking resin and as a photoinitiator for UV curable coating and ink compositions.Also provided is a specified ultraviolet radiation curable coating composition. The composition comprises a mixture ofA. about 4.5 to 49.5% by weight of the novel amine-modified polyester described above;B. about 50 to 95 percent by weight of a photopolymerizable or photocrosslinkable ethylenically unsaturated compound; andC. about 0.5 to 25 percent by weight of a photoinitiator.The photoinitiator is selected from the group consisting of benzil, lower alkyl substituted benzil, benzoin ethers, haloalkyl ketones, aromatic ketones, lower alkyl substituted aromatic ketones, aromatic ketones in combination with amines, and mixtures thereof. The ethylenically unsaturated compound is most preferably selected from the group consisting of glycidyl acrylate, glycidyl methacrylate, methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, and mixtures thereof. The coating composition provided by the present invention gives clear insoluble coatings which are useful as protective and/or decorative coatings.
