A pre-dispersion composition comprising (i) a silsesquioxane; (ii) a dispersing agent; and (iii) a curable resin.

Two-part aqueous coating compositions as well as methods of using thereof are described. The first coating component can comprise one or more polymers and the second coating component can comprise a flocculant. The first coating component and the second coating component can be provided as separate aqueous compositions. The first coating component and a second coating component that can be co-applied (e.g., simultaneously or sequentially) to a surface form a rapid set coating.

Photo-activated polymers and co-polymers exhibit colors in the visible spectrum when photo-activated. The photo-active polymers, co-polymers and combinations thereof may be utilized in articles to impart color to the articles. For example, the photo-active polymers may be utilized in printing technology, such as in 2D printing and/or in 3D-printing methods to impart colors to articles.
