Abstract
The present invention provides a novel composition useful for restoring a fabric in need of restoration due to compression thereof, for example the fabric backing of a printing blanket, in particular a smashed printing blanket. The composition includes a sulfated fatty alcohol anionic surfactant, a sulfonated alkylaryl anionic surfactant, and an organic phosphate ester surfactant. Also provided is a printing blanket, to which the novel composition has been applied, as well as an improved method for restoring a printing blanket.
Claims18
A thick viscous liquid composition useful for restoring a printing blanket having an unmarred or unbroken elastomeric face but in need of restoration due to compression of the fabric backing thereof, said composition consisting essentially of as ingredients in a water solvent,
- (a) about 1-10 of a sulfated fatty alcohol anionic surfactant, from about 3 to about 20% of a sulfonated alkylaryl anionic surfactant, and from about 0.5 to about 10% of an organic phosphate ester surfactant, and
- (b) either (1) from about 1 to about 10% of a nonionic surfactant, or (2) from about 0.5 to about 2% of a water-soluble salt and from about 1 to about 8% of an amphoteric surfactant other than an amphoteric organic phosphate ester surfactant;
- wherein said ingredients are individually present in an amount sufficient to provide said restoring upon a sufficient amount of said composition being applied to said fabric backing.
The composition of clami 1, wherein said sulfonated alkylaryl anionic surfactant is an alkali metal dodecylbenzene sulfonate.
