Abstract: ABSTRACT OF THE DISCLOSURE    The  invention  concerns  a  heat-sensitive  transfer recording material to be used for heat-sensitive transfer recording such as thermal printer, and relates to a heat-sensitive transfer ribbon having a heat-fusible ink layer provided on the surface of a polyester base film.  And, its  specific  feature  resides  in  providing  a  heat-sensitive protective layer containing a modified product of a 4-methyl-1-pentene polymer on the other surface of the polyester base film.   The heat-sensitive  transfer ribbon  of  the  present  invention  having  such  heat-sensitive protective layer provided thereon has excellent heat  resistance  and  therefore  has  good  high-speed transfer  performance  and  can  also  prevent  sticking.      Also, since the base film can be made thin, transmission of heat is rapid, whereby high-speed and yet clear image formation is made possible.

Abstract: A pharmaceutical oral controlled release multiple-units formulation in which individual units comprise cross-sectionally substantially homogeneous cores containing particles of a sparingly soluble active substance, the cores being coated with a coating which is substantially resistant to gastric conditions, but which is erodable under the conditions prevailing in the small intestine, in particular an enteric coating which is substantially insoluble at a pH below 7 such as Eudragit<sup>0</sup> S (an anionic polymerisate of methacrylic acid and methacrylic acid methyl ester), is prepared by a process comprising comminuting an active substance together with a substance which is readily soluble in intestinal fluids such as an anionic detergent to obtain particles containing the active substance in intimate admixture with the readily soluble substance, combining the resulting particles into cross-sectionally substantially homogeneous cores together with components which accelerate the disintegration of the cores in intestinal fluids such as talc and sucrose, coating the individual cores with the coating, and combining a multiplicity of the coated cores into a capsule or tablet formulation.As the coating is erodable in an alkaline environment only, the active substance is not released until the units arrive at a section ofthe small intestine with an alkaline pH. Thus, a reduction and delay of the peak plasma concentration is obtained without affecting the extent of drug availability.A coating of the above-defined type may also be used when the active substance is a substance which exerts an irritating effect on the gastric mucosa and/or is unstable in an acidic environment.
