    • The present invention is directed to compositions and a process leading to colorless or light colored aqueous phicinol-formaldelhyde resoles. Unlike previous technologies, these compositions lead to clear storage stable fast curing, high molecular weight resins. These materials are also capable of producing composite wood panels with superior water absorption and thickness swell test results when soaked in water. The invention essentially consists of an aqueous copolymer of phenol, formaldehyde, and a phenolic carboxylate (e.g. salicylic acid). Methylol phenols are formed under alkaline conditions in the presence of metal chelating agents. These are then condensed into a polymer under alkaline, neutral or acidic conditions. The finished aqueous polymer solution is then acidified to the desired pH using a benzoic acid or a phelnol-carboxylic acid.
    • 本发明涉及组合物和一种导致无色或浅色的含有精氨酸 - 正癸醛水溶液的方法。 与以前的技术不同,这些组合物导致清晰的储存稳定快速固化,高分子量树脂。 这些材料也可以生产复合木板,当浸泡在水中时具有优异的吸水性和厚度溶胀试验结果。 本发明基本上由苯酚,甲醛和酚羧酸酯(例如水杨酸)的含水共聚物组成。 在金属螯合剂存在下,在碱性条件下形成羟甲基酚。 然后将它们在碱性,中性或酸性条件下浓缩成聚合物。 然后使用苯甲酸或吡咯烷羧酸将最终的聚合物水溶液酸化至所需的pH。

    • A method of producing a resist pattern on a substrate using a precursor which comprises a coating composition which includes a heat sensitive polymeric substance having functional groups Q thereon (wherein groups Q may be siloxane or optionally substituted fluoroalkyl groups) wherein groups Q cause the polymeric substance to have a reduced adhesive interaction with ink for use in waterless lithographic printing compared to aid polymeric substance in the absence of said groups, the method including the step of causing the patternwise application of heat to said coating composition and optional development thereby to define ink accepting areas in heat exposed areas and non-ink accepting areas in non-exposed areas.
    • 一种使用前体制备抗蚀剂图案的方法,该前体包括包含其上具有官能团Q(其中基团Q可以是硅氧烷或任选取代的氟烷基)的热敏聚合物质的涂料组合物,其中基团Q引起聚合物质 与没有所述基团的帮助聚合物质相比,与无水平版印刷中使用的油墨具有降低的与油墨的相互作用,该方法包括对所述涂料组合物进行图案加热以及任选的显影步骤,从而定义油墨接受 非暴露地区的曝光区域和非油墨接收区域的区域。
