2-3-Dihydro-1H-phenalene-2-amino compounds of the formula
some of which are new, e.g., 2-3-dihydro-2-(N,N-di-n-propylamino)-1H-phenalen-5-ol, and pharmaceutically acceptable salts of such compounds have been found to be useful anti-psychotic drug compounds.
The invention relates to a process for the preparation of a polyamide/aromatic polyester composition having high temperature resistance and toughness. The composition is obtained by using polytetramethylene adipamide as polyamide and effecting the mixing of the polyamide and the aromatic polyester in the melt in the presence of paratoluene sulphonic acid.

A liquid crystalline polymer-metal laminate having one or more layers of a liquid crystal polymer film and one or more layers of a metallic foil, which when placed in a press and subjected to a pressure of between 5 to 100 bar, and a temperature greater than the melt point of the polymer film and less than the degradation temperature, and at a residence time of 0.5 to 1000 seconds produces a laminate having a minimum peel strength of 10 Newtons per centimeter and a dimensional stability of less than 0.2 %. Optionally, fiber reinforcement fabric can be employed in the laminate to provide increased mechanical strength or dimensional stability. Such a laminate is particularly useful for circuit boards.

The present invention provides a black dyestuff for inkjet recording which exhibits a good achromaticity as well as a good light-resistance and a recording liquid containing the black dyestuff.
In other words, the recording liquid for inkjet contains a metal chelated azo dyestuff the free acid group of which is represented by the following general formula (1) and optionally other water soluble dyestuffs:
(wherein the general formula (1) represents a compound having at least one or more hydrophilic group per molecule; M represents an arbitrary metal; A, B and C each independently represents an aromatic ring which may have arbitrary substituents; D represents an aromatic ring which may have arbitrary substituents other than azo group; m represents an integer of 0 to 1; n represents an integer of from 0 to 3; p represents an integer of from 0 to 2; q represents an integer of from 1 to 3, with the proviso that if there are a plurality of B's, they may be the same or different; R1 and R2 each independently represents hydrogen atom or arbitrary substituent; M can take tridentate or higher coordination in which M may take arbitrary ligand-to-metal coordination at arbitrary substituent or bond in the general formula (1) or with arbitrary ligands; and a metal ion may be further coordinated to A and B, B and B which are adjacent to each other with an azo group interposed therebetween if there are a plurality of B's or B and C in the form of -O-M-O-).
本发明提供了一种具有良好消色差和耐光性的喷墨记录用黑色染料,以及一种含有该黑色染料的记录液。
换句话说,喷墨记录液含有一种金属螯合偶氮染料,其游离酸基由以下通式(1)表示,还可选择其他水溶性染料:
(其中,通式(1)代表每分子至少有一个或多个亲水基团的化合物;M 代表任意金属;A、B 和 C 各自独立地代表一个芳香环,该芳香环可以有任意取代基;D 代表芳香环,可具有除偶氮基团以外的任意取代基; m 代表 0 至 1 的整数; n 代表 0 至 3 的整数; p 代表 0 至 2 的整数; q 代表 1 至 3 的整数,但如果有多个 B,它们可以相同或不同;R1和R2各自独立地代表氢原子或任意取代基;M可以是三叉配位或更高配位,其中M可以在通式(1)中的任意取代基或键上进行任意配体对金属配位或与任意配体配位;如果有多个B或B和C以-O-M-O-的形式存在,金属离子可以进一步与A和B配位,B和B相邻,中间夹有偶氮基团。)
