Abstract

LAS MICROCAPSULAS DE NUEVO TIPO SE CARACTERIZAN DE TAL MODO, QUE SU PARED SE COMPONE DE PRODUCTOS DE TRANSFORMACION DE COMPUESTOS DE GUANIDINA Y POLIISOCIANATOS O DE FORMA QUE CONTIENEN TALES PRODUCTOS DE TRANSFORMACION. LAS DISPERSIONES QUE CONTIENEN ESTAS MICROCAPSULAS PUEDE SER ELABORADAS DE TAL MODO QUE SE DISPONE DE UN PROCEDIMIENTO CONOCIDO PARA LA ELABORACION DE DISPERSIONES DE MICROCAPSULAS A BASE DE POLIISOCIANATOS Y AMINAS, AMINOALCOHOLES O COMPUESTOS HIDRACINA EN LUGAR DE AMINA, AMINOALCOHOLES O COMPUESTOS DE HIDRACINA, ASI COMO COMPUESTOS DE GUANIDINA. LA PRESENTE INVENCION SE REFIERE TAMBIEN A PAPELES DE CALCO LIBRES DE CARBON QUE CONTIENEN UN PRECURSOR DE SUSTANCIA COLORANTE EN LAS MICROCAPSULAS, CUYAS PAREDES SE DISPONEN A BASE DE PRODUCTOS DE TRANSFORMACION DE COMPUESTOS DE GUANIDINA Y POLIISOCIANATOS O CONTIENEN TALES PRODUCTOS DE TRANSFORMACION.
