PROBLEM TO BE SOLVED: To provide a method for producing a pale liquid mixture of organic isocyanates with storage stability having carbodiimide groups and/or uretonimine groups, capable of forming the liquid mixture of the isocyanates with a low color number and the storage stability.;SOLUTION: This method comprises partially carbodiimidizing one or more kinds of organic isocyanates having a Hazen color number of ≤100 APHA by using a phospholine-type catalyst and then stopping carbodiimidization reaction in case of production of the organic isocyanates having the carbodiimide groups and/or the uretonimine groups, wherein the carbodiimidization reaction is stopped by using an alkylating agent.;COPYRIGHT: (C)2006,JPO&NCIPI
