摘要： Appliances for the partial dyeing of hair are intended, for example, to serve for dyeing individual strands of hair, in order to achieve stylish effects as a result of the color contrast.To ensure that the appliance is mastered even by less experienced staff and that dyeing is simplified and speeded up, the appliance has at least one guide prong (14), which is provided in its interior with a dye-feed bore (16) and on at least one side, spaced at a distance from the prong end (19), with at least one peripheral dye-outlet orifice (21). The appliance also includes a dye container (3), which is connected to the dye-feed bore (16) of the guide prong (14) and out of which the dye can be expressed by means of pressure, and at least one masking prong (22) which is located spaced at a distance from the guide prong and covers hair not to be dyed and which is located, approximately transversely to the working direction of the guide prong (14), next to the latter.

摘要： The present invention is directed to a method for the production of plastics, including foams, containing urethane groups and predominantly isocyanurate groups by reacting polyesters having a molecular weight of from 350 to 10,000, and containing at least two hydroxyl groups and containing phthalic acid residues and, optionally, other polyhydroxyl compounds having a molecular weight of from 400 to 10,000 and/or chain extenders having a molecular weight of from 32 to 400 with an excess of polyisocyanates in the presence of isocyanate-trimerization catalysts and optionally blowing agents, foam stabilizers and other additives, the improvement characterized in that polyesters are used whose acid components comprise at least 50%, by weight, phthalic acid residues and wherein 10 to 49%, preferably 20 to 40%, by weight, of the isocyanate groups react to form urethane groups and 51 to 90%, preferably 60 to 80%, by weight, of the isocyanate groups react to form isocyanurate groups.
摘要翻译：本发明涉及通过使分子量为350至10,000的聚酯与含有至少两个羟基并含有邻苯二甲酸残基的聚酯反应生产包含聚氨酯基团和主要为异氰脲酸酯基团的泡沫塑料的方法，以及，任选的其它分子量为400至10,000的多羟基化合物和/或分子量为32-400的扩链剂和过量的多异氰酸酯在异氰酸酯 - 三聚催化剂和任选的发泡剂，泡沫稳定剂和其他添加剂的改进特征在于使用聚酯，其酸组分包含至少50重量％的邻苯二甲酸残基，其中10至49重量％，优选20至40重量％的异氰酸酯基团反应形成氨基甲酸酯基团和51-90％，优选60-80％重量的异氰酸酯基团反应形成异氰脲酸酯基团。
