摘要:
A multi-colored image recording method capable of producing in repetition clear multi- and full-colored images having high density on a number of receiving sheets is disclosed, in which a thermosensitive image transfer sheet including four leuco dye layers respectively containing yellow, magenta, cyan and black leuco dyes that can be respectively colored in yellow, magenta, cyan and black, and a color developer layer containing a color developer capable of developing the leuco dyes in the four colors is superimposed on a receiving sheet and heat is applied to the thermosensitive image transfer sheet in accordance with the desired color tone information, whereby the leuco dyes and the color developer are transferred from the image transfer sheet onto the receiving sheet so as to selectively overlap the leuco dyes and the color developer, thereby producing multi-colored images by the coloring reaction therebetween.
摘要:
A heat-sensitive recording medium including:(a) a transferring sheet which includesa first substrate,a lower layer provided over the first substrate and comprised of a discoloring agent and a solid ink having a first color, andan upper layer provided above the lower layer and containing a leuco-compound capable of coloring in a second color which is different from the first color by reaction with a developer at such a first temperature that at least one of said leuco-compound and said developer can melt but that neither the discoloring agent nor the solid ink can melt, the leuco-compound being incapable of coloring upon contact with the developer in the presence of the discoloring agent at such a second temperature that both of the discoloring agent and the solid ink can melt; and(b) a receiving sheet which includesa second substrate, anda developing layer provided over the second substrate and containing the developer. When the recording medium is subjected to thermal recording temperatures with the upper layer being maintained in thermal contact with the developing layer, there are formed a first image developed by the contact between the leuco-compound and the developer at the first temperature and a second, fused image of the solid ink at the second temperature, the first and second images being received by the receiving sheet.

摘要:
This invention relates to a method of recording an image, characterized by superposing a heat-sensitive transfer medium on a plain paper and heating the medium thereby transferring a leuco dye from a leuco dye-containing transfer layer and a developer from a developer-containing transfer layer respectively onto the plain paper to react the leuco dye and the developer, said heat-sensitive transfer medium being prepared by having a transfer layer containing a leuco dye as the main component and a transfer layer containing a developer as the main component respectively applied on a single substrate or two separate substrates.
摘要:
A heat-sensitive transfer medium of this invention comprises the combination of a transfer sheet which has on one surface of a substrate a transfer layer consisted essentially of a leuco dye and a binder resin and is provided on its opposite surface with a 0.2-5 .mu.m-thick polyfluorocarbon-containing layer with a receiving sheet which is provided on the substrate with a receiving layer consisting essentially of a developer for the leuco dye and the binder resin, and further comprises adding a porous filler (oil absorption: 50-300 ml/100 g) to the receiving layer and/or the transfer layer.

The invention provides a multi-piece solid golf ball having a core, an envelope layer which encloses the core, an intermediate layer which encloses the envelope layer, and a cover which encloses the intermediate layer and has formed on a surface thereof a plurality of dimples. The core is formed primarily of a rubber material, the envelope layer is formed primarily of a specific resin mixture, the intermediate layer is formed primarily of a resin material, and the cover is formed primarily of polyurethane. The intermediate layer and the cover have surface hardnesses (Durometer D hardness) which satisfy the relationship: intermediate layer surface hardness>cover surface hardness. The golf ball has an excellent flight performance and controllability that are acceptable to professionals and other skilled golfers, while also having an excellent durability to cracking on repeated impact and an excellent scuff resistance.

A metallic gasket including a base plate having a convex metal bead formed, by bending the base plate, between a combustion chamber opening and on the outer periphery portion of the base plate, and a first thickness-increased portion formed thicker than the remaining portions of the base plate to provide a difference in thickness, by which a surface pressure is made to concentrate on the first thickness-increased portion to seal a joint between a cylinder head and a cylinder block when the metallic gasket is disposed between the joint surfaces of the cylinder head and the cylinder block and fastened by clamping bolts. An elastic sealing material is fixed to the convex portion of the metal bead and filled in a concave portion on the reverse side of the base plate to form a rubber bead, and the sealing material is deformed under compression in the through-thickness direction in cooperation with the deformation of the metal bead when the gasket is fastened with clamping bolts. This gasket reduces production cost and preserves a stable sealing performance for extended periods of time.
