Abstract

A composition for forming a biocidal coating is provided. The composition has a log reduction of at least 2 and a CIEL*a*b* delta E*value less than about 30.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 782,044, filed December 19, 2018, which is based upon the contents of that application and is incorporated herein by reference in its entirety. Background technique [0003] A coating or composition (eg, lacquer) can be applied to a substrate or surface or stored in a container. Over time, a coating or composition can be exposed to a variety of undesirable contaminants, such as bacteria, viruses, mildew, mold, fungi, algae, and the like. Exposure to these contaminants can render the coating or composition visually objectionable or unsuitable for a particular application or present a health hazard. Accordingly, it may be advantageous to mitigate the ability of undesired contaminants to thrive when in contact with a coating or composition. Contents of the invention [0004] According to various embodiments...
