Abstract
Abstract Disclosed is a heat and pressure sensitive recording material for recording and duplicating comprising an up sheet I and a down sheet II, wherein the up sheet I is coated on the surface with a composition A comprising a colorless electron donative organic compound 1 and an acidic organic compound 2 which develops the color of said compound 1 when heat is applied and is coated on the other side facing the down sheet II with a composition B comprising said compound 1, an encapsulated one 1' of said compound 1 and a hot melt material 3, and the down sheet II is coated on the side facing the up sheet I with a composition C comprising said organic compound 2. The heat and pressure sensitive recording material may further insert between the up sheet I and the down sheet II at least one middle sheet III coated with the composition C one one side and with the composition C on the other side.
