    • Disclosed is a radiation curable composition which includes: (a) an unsaturated ester compound, and (b) a pulverizable vinyl ether compound. The unsaturated ester compound is characterized as having a plurality of unsaturated ester groups per molecule. The pulverizable vinyl ether compound is characterized as including at least one of the following: (a) a compound having an average of greater than 1.0 reactive vinyl ether groups per molecule, and (b) a vinyl ether-containing group bonded to the unsaturated ester compound such that there is an average of at least 1.0 reactive vinyl ether group per molecule. The unsaturated ester compound, the vinyl ether compound and/or a mixture thereof is treated with a reducing agent so as to decompose destabilizing agents present therein that would initiate premature polymerization of the vinyl ether compound. Accordingly, in the stabilized radiation curable coating compositions of this invention, polymerization of the vinyl ether compound is substantially avoided until blended with the unsaturated ester compound and exposed to radiation.
    • 公开了一种可辐射固化组合物,其包括:(a)不饱和酯化合物和(b)可粉化的乙烯基醚化合物。 不饱和酯化合物的特征在于每分子具有多个不饱和酯基。 可粉碎的乙烯基醚化合物的特征在于包括以下至少一种:(a)每分子平均具有大于1.0个反应性乙烯基醚基团的化合物,和(b)与不饱和酯键合的含乙烯基醚基团 化合物,使得每个分子平均具有至少1.0个反应性乙烯基醚基团。 用还原剂处理不饱和酯化合物,乙烯基醚化合物和/或它们的混合物,以分解其中存在乙烯基醚化合物过早聚合的不稳定剂。 因此,在本发明的稳定的可辐射固化涂料组合物中,基本上避免了乙烯基醚化合物的聚合,直到与不饱和酯化合物共混并暴露于辐射。

    • Coating compositions are formulated using a polyol with a hydroxyl functionality of at least three modified by reaction with a glycidyl ether in proportion of about 0.1 to about 4, preferably from about 0.2 to about 2 moles of glycidyl ether per mole of polyol, with which is combined, as curing agent, a compatible aminoplast resin. When the polyol is trimethylol ethane, for example, and is so modified with allyl or butyl glycidyl ether, for example, and is so modified with allyl or butyl glycidyl ether, for example, and the compositions contain a methylated melamine formaldehyde condensate as curing agent, they are especially suitable for clear top coating surfaces of wood or flat woodstock containing printing inks to simulate woodgrain, to provide a durable coating highly adherent to the inks as well as the cellulosic materials. The compositions may contain high solids content yet they are stable on storage without development of crystallization and are reducible or thinnable with water.
    • 涂料组合物使用具有至少三个羟基官能度的多元醇配制,所述多元醇通过与缩水甘油醚反应而改性,其比例为每摩尔多元醇约0.1至约4,优选约0.2至约2摩尔缩水甘油醚, 组合,作为固化剂,相容的氨基塑料树脂。 例如,当多元醇为三羟甲基乙烷并用烯丙基或丁基缩水甘油醚进行改性时,例如用烯丙基或丁基缩水甘油醚进行改性,组合物含有甲基化三聚氰胺甲醛缩合物作为固化剂 ,它们特别适用于含有印刷油墨的木材或扁平木材的透明顶部涂层表面以模拟木纹,以提供高度贴附于油墨以及纤维素材料的耐用涂层。 组合物可以含有高固体含量,但它们在储存时稳定而不发展结晶,并且可用水还原或稀释。
