A method for sanitizing flush toilets wherein a sanitizing agent and a triphenylmethane dyestuff are dispensed separately from a dual dispensing means into the toilet flush water. The dyestuff is resistant to attack by the sanitizing agent and therefore provides an aesthetically pleasing color to the water remaining in the bowl during the time period between flushes.

A method for sanitizing flush toilets wherein a sanitizing agent and a triphenylmethane dyestuff are dispensed into the toilet flush water. The dyestuff is resistant to attack by the sanitizing and therefore provides an aesthetically pleasing color to the water remaining in the bowl during the time period between flushes. The dyestuff has the general Formula I, wherein:
X represents hydrogen or the group S03M;
Y represents hydrogen or hydroxy;
R and R' both represent m-(MSO3)-benzyl where M represents an alkali metal cation,.an ammonium ion or an alkaline earth metal cation, and in the event that X is MS03, R and R1 can furthermore be defined by R representing benzyl optionally substituted in the benzene ring by S03M in which M is as defined above and R1 representing a non-tertiary C1 to C4 alkyl. The invention also deals with novel members of said general Formula 1.
一种冲水马桶消毒方法,在冲水马桶中加入消毒剂和三苯甲烷染料。该染料能抵御消毒剂的侵蚀,因此在冲水间隔期间能为冲水马桶中残留的水提供美观的颜色。染料的通式为 I,其中
X 代表氢或基团 S03M;
Y 代表氢或羟基
R和R'都代表m-(MSO3)-苄基,其中M代表碱金属阳离子,.铵离子或碱土金属阳离子,如果X是MS03,R和R1可进一步定义为R代表在苯环上任选被S03M取代的苄基,其中M如上定义,R1代表非三级C1至C4烷基。本发明还涉及上述通式 1 的新型成员。
