Abstract
MATERIAL TERMOSENSIBLE DE IMPRESION EN COLOR COMPRENDE, EN UNA CAPA CROMOGENA, UN PRECURSOR DE TEÑIDO INCOLORO DADOR DE ELECTRONES (POR EJEMPLO, UN FLUORANO) Y, COMO ACEPTOR DE ELECTRONES, UNA BISTIOUREA, EN UNA CANTIDAD DEL 20 AL 500 % POR PESO DEL PRECURSOR, PREFERIBLEMENTE CON LA FORMULA O EN DONDE R1 Y R2 SON CADA UNO OPCIONALMENTE ALQUIL O ARILO SUBSTITUIDO, R3 Y R4 SON CADA UNO OPCIONALMENTE ARILO SUBSTITUIDO, Y X ES ALQUILENO O ALQUILENO O ARILENO. SE MUESTRAN 25 DE TALES COMPOSICIONES. LA BIOTIOUREA SE UTILIZA PREFERIBLEMENTE COMO PARTICULAS NO SUPERIORES A 3 MICROM. TAMBIEN SE PUEDE INCLUIR UN AGENTE SENSIBILIZADOR. LOS COMPONENTES SE DISPERSAN EN UNA SOLUCION ACUOSA DE UN LIGANTE POLIMERICO RECUBIERTO EN UN SOPORTE, EL RECUBRIMIENTO SE SECA Y SE SATINA; SE PUEDE AÑADIR UNA CAPA PROTECTORA O DE RECUBRIMIENTO POSTERIOR. EL MATERIAL ES UTIL EN UNA TERMOIMPRESORA.
