resumo composição indicadora de umidade não aderente para aplicação em um substrato polimérico a presente invenção envolve uma composição de revelação de cor, que contém pelo menos três componentes principais: (1) um leuco-corante ou uma combinação de corantes leucos, (2) um agente revelador de cor ou uma combinação de reveladores de cor que podem formar complexos coloridos com corantes leucos (3) um dessensibilizante para remover temporariamente o efeito do relevador de modo que o corante leuco apareça em sua forma incolor. um aglutinante opcional pode ser incluído de modo a que a composição possa ser aplicada a um substrato como uma tinta. a composição da tinta pode ser aplicada a substratos poliméricos sintéticos e outros substratos que são incorporadas nos artigos absorventes e produtos de cuidados pessoais. 1/1 The invention describes a color-developing composition that contains at least three major components: (1) a leuco dye or a combination of leuco dyes, (2) an color-developer or a combination of color-developers that can form colored complexes with the leuco dyes, and (3) a desensitizer to temporarily remove the effect of the developer so the leuco dye appears in its colorless form. An optional binder may be included so that the composition may be applied to a substrate as an ink. The ink composition may be applied to synthetic polymeric substrates and other substrates that are incorporated into absorbent articles or personal care products.
