Zusammenfassung:	A composition for a dry blend powder coating is disclosed, allowing to create single layer gradient effects. The dry blend powder coating includes a first part of about 40 to 60 % by weight of a polyester resin having carboxylic groups, having a first pigment, and a second part of about 40 to 60 % by weight of: a glycidyl-acrylic polymer resin, an acrylic polymer resin having carboxylic groups , or a combination thereof, having a second pigment. The acrylic polymer includes carboxylic groups having an acid value of approximately 40 mgKOH/g, and glycidyl-acrylic polymer resin having an EEW value of approximately 700 g/eq. In an embodiment the polyester resin has an acid value of approximately 30 mgKOH/g.
