A two-component curable epoxy resin system including a dye solution. The resin system includes an epoxy resin component containing at least 80% by weight of a polyglycidyl ether of a polyphenol. The system also includes a hardener mixture containing mainly polyethylene tetraamines. The system includes triethylene diamine in specific amounts as a catalyst. The system has beneficial curing characteristics with desired color that make it useful for producing fiber-reinforced composites in a resin transfer molding process.

The present application relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two constituents: at least one chromophore constituent and at least one polymeric constituent. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to light, or they may absorb light to reflect these same shades. This disclosure also relates to laundry care compositions including but not limited to liquid and/or powder laundry detergent formulations and rinse added fabric softening (RAFS) compositions that comprise such whitening agents.
