Zusammenfassung:Photocurable compositions that have a color change during curing and methods of preparation and use of such compositions. More particularly, the present invention relates to photocurable compositions that that have a color change during curing and are useful for forming topographical features, e.g., spacer features, and/or fold protection coatings on a portion of a membrane surfaces, and particularly on membranes used in osmosis and reverse-osmosis applications, such as membrane filters. Composiciones fotocurables que tienen un cambio de color durante el curado y métodos de preparación y uso de dichas composiciones. Más particularmente, la presente invención se refiere a composiciones fotocurables que tienen un cambio de color durante el curado y son útiles para formar características topográficas, p. ej. características de espaciadores, y/o recubrimientos de protección contra el pliegue en una porción de una superficie de membrana, y particularmente en membranas que se usan en aplicaciones de ósmosis y ósmosis inversa, como filtros de membrana.
