Abstract
The pressure sensitive recording sheet is partially desensitized by applying an improved desensitizer to a predetermined area thereof. The improved desensitizer comprises a reaction product produced by the reaction of ammonia, amines, diamines or polyamines with glycidyl esters or glycidyl ethers. The improved desensitizer is hydrophobic and soluble in an oil vehicle.
