摘要:
A color developer containing a combination of zinc oxide, at least one salicylic acid or nuclear substituted salicylic acid, and at least one metal silicate as an inorganic pigment, and a recording unit having a layer of the color developer. The color developer has a high developing ability and is capable of forming a distinct color having a high light resistance when it is contacted with a color former.
摘要:
This invention provides a novel recording sheet having improved developing ability and resistance to light irradiation and which can be produced easily and economically. A developer layer coated on a support of the recording sheet contains a reacted compound between an alkali metal salt of a phenol resin and a water soluble metallic compound.
摘要:
A recording sheet comprising a support having thereon a color developer layer containing (1) a metal compound of an aromatic carboxylic acid and (2) at least one of gelatin or a gelatin derivative, the metal compound of an aromatic carboxylic acid being capable of forming a colored image when reacted with a color former.
摘要:
A recording sheet comprising a support having a developer layer thereon, the developer layer containing a phenol resin and an aqueous emulsion of an oily material and produced by admixing a coating composition containing a phenol resin and an aqueous emulsion of an oily material and coating the resulting mixture on a support.
摘要:
A process for the production of a color developer comprising reacting an alkali metal salt of an aromatic carboxylic acid and a water-soluble metal salt in the presence of clay and a water-insoluble aluminum compound.
摘要:
A color developer is disclosed which, when contacted with a color former, is capable of forming a distinct color, the color developer comprising a metallic compound of an aromatic carboxylic acid. Suitable metals are, for example, those of the following groups of the Periodic Table: Ib, IIa, IIIb, IVb, VIa, VIIa and VIII. A recording sheet employing the color developer is also disclosed.

There is provided a waterproof connector in which swing of electric wires inside a rear holder can be prevented, and insertion of the rear holder into a connector body can be easily performed with a small force. The waterproof connector includes a connector body 2 having a terminal containing room 21 in which a terminal metal fitting 9 of an electric wire 7 is contained, a waterproof plug 3 which is fitted to the electric wire 7 at a wire withdrawing side 23 of the connector body 2 and assembled to the wire withdrawing side 23 of the connector body 2, and a rear holder 5 which is mounted on the wire withdrawing side 23 of the connector body 2 thereby to prevent drop of the waterproof plug 3 from the connector body 2. The rear holder includes a pair of half bodies which are separated as a first holder body 51 and a second holder body 52, wire containing recesses 53, 54 which contain respective semi-circular portions of the electric wire are respectively formed in the first holder body 51 and the second holder body 52, and the first holder body 51 and the second holder body 52 are individually mounted on the wire withdrawing side 23 of the connector body 2 to be combined together.
