Abstract: One of the purposes of the present invention is to provide a blocking agent for blocking an isocyanate group to thereby prepare an isocyanate compound which has excellent water resistance and is react with another polymerizable compound to be cured at a relatively low temperature; and another purpose is to provide a blocked isocyanate having an isocyanate group blocked with the blocking agent. The present invention provides a blocking agent for blocking an isocyanate group, wherein the blocking agent is an organic silicon alcohol having an organic group bonded to a silicon atom and said organic group is capable of forming a ?-silyl cation together with the silicon atom. In a preferred embodiment, the present invention provides a blocking agent which is an organic silicon alcohol represented by the general formula (1).
