摘要

This invention provides a removable coating, comprising one or more light filtering components and a binder system having an average acid value from 15 to 39, wherein said binder system comprises:
(a) a first water-resistant acrylic-based water-borne resin having an acid value not above 35, and
(b) a second acrylic-based water-borne resin being water-soluble at a pH above 8. This coating is especially suitable for greenhouses, and can be cleaned by means of a weak base in the absence of a complex former.
