A method of making a solar heat energy collecting system which comprises: forming a potentially foamable, resinous base layer containing a blowing agent; applying a printing composition to the surface of the potentially foamable, resinous base layer in the form of at least one continuous path extending from one edge point to another edge point of the potentially foamable, resinous base layer, the printing composition comprising a blowing inhibitor and a release agent; applying a top surface layer to the surface of the printed potentially foamable, resinous base layer which adheres thereto except in those areas containing the blowing inhibitor and release agent; heating the potentially foamable, resinous base layer to decompose or to activate the blowing agent in those portions of the potentially foamable, resinous base layer not lying under the blowing inhibitor and release agent, whereby such portions are blown and expand to extend and stretch upwardly so as to form upright walls of foamed, relatively lower density resinous material extending substantially vertically from the main portion of the resinous base layer, while those other portions of the potentially foamable, resinous base layer lying under the blowing inhibitor and release agent remain relatively unaffected; and supplying a fluid medium to those printed areas of the potentially foamable, resinous base layer lying over the blowing inhibitor and release agent, whereby the top surface layer is moved upwardly to form at least one continuous open channel extending from one edge point of the resinous base layer to another edge point of the resinous base layer and capable of conducting a heat transfer fluid medium therethrough. The inventive concept also relates to the solar heat energy collecting systems resulting from such methods.

Methods of obtaining deep through penetration of colorants into firmed printable gelled plastisol or sintered dry-blend polyvinyl chloride compositions which comprise: applying a transfer paper or other substrate coated with a sublimable disperse dye to the surface of a firmed printable gelled plastisol or sintered dry-blend polyvinyl chloride composition, wherein the polyvinyl chloride resin is in particulate form having an average particle size of from about 0.5 micron to about 420 microns and contains specified percentages of plasticizer and stabilizer; applying heat thereto in the range of from about 300.degree. F. to about 430.degree. F. for a period of time of from about 6 seconds to about 20 seconds, whereby the sublimable disperse dye sublimes and, while in the sublimed vapor phase, penetrates deeply into the firmed printable gelled plastisol or sintered dry-blend polyvinyl chloride composition; removing the transfer paper or other substrate, leaving the disperse dye in the firmed printable gelled plastisol or sintered dry-blend polyvinyl chloride composition; applying a resinous polymer composition to the surface of the dyed firmed printable gelled plastisol or sintered dry-blend polyvinyl chloride composition as a wear layer; and applying heat to the dyed firmed printable gelled plastisol or sintered dry-blend polyvinyl chloride composition in the range of from about 310.degree. F. to about 470.degree. F. to fuse the polyvinyl chloride resin.
