Abstract
Provided is a coating composition that include a first resin having a Tg above about 25° C. and a second resin having a Tg above about 50° C. The coating composition and/or resins thereof are at least partially hydrolysable in a hot caustic solution. Further provided are a method for applying the coating composition to a label substrate, a label substrate coated with the coating composition, and a recycling method. Sleeve labels for articles such as containers may be formed from label substrates by forming a bonded seam with the coating composition. The coating composition maintains the bond in the seam during sleeve label shrinking and during article life. Label removal during recycling is relatively easy, as the coating composition in the seam de-bonds in a hot caustic solution.
