The invention relates to a compound, comprising at least three functionalities, that is (a) a sulfonate or sulfate group of the formula —(O)
d
—SO
3
M with d=0 or 1 and M=hydrogen or a monovalent metal cation or the corresponding fraction of a polyvalent metal cation, (b) a (meth)acryl group, and (c) either (c1) at least one further (meth)acryl group or an inorganically condensable group, and/or (c2) a further carboxylic acid function, and/or (c3) a function which increases the refractive index of a material produced from the compounds, that is a thioether group, with the proviso that a sulfonate or sulfate group and a (meth)acrylate group are separated from one another in a silicon-free compound via a hydrocarbon-containing group, the carbon chain of which is either interrupted by O, S or NH or contains a linking group.
本发明涉及一种化合物,包括至少三种官能团,即(a)公式为—(O)d—SO3M的磺酸盐或硫酸盐基团,其中d=0或1,M=氢或单价金属阳离子或相应的多价金属阳离子的分数,(b)(甲基)丙烯酸基团,以及(c)(c1)至少一种进一步的(甲基)丙烯酸基团或无机可凝聚基团,和/或(c2)进一步的羧酸功能,和/或(c3)增加化合物所产生材料的折射率的功能,即硫醚基团,条件是磺酸盐或硫酸盐基团和(甲基)丙烯酸酯基团在无硅化合物中通过含碳氢化合物的基团分离,其碳链被O,S或NH中断或包含一个连接基团。
