[Prior Art] It has been known that polyurethane elastomer compositions (solutions) are used for producing porous sheet materials (Japanese Patent Publication No. 46-25269, Japanese Patent Publication No. 58-5931, etc.). [Problems to be Solved by the Invention] Polyurethane compositions used for such sheet materials are polyurethane compositions that provide a porous sheet material with excellent surface smoothness, low sheet density, and low shrinkage, so-called wet film forming properties. There is a demand for something superior. [Means for Solving the Problems] As a result of intensive study by the present inventors in order to disturb the polyurethane composition that satisfies these requirements, the present inventors found that a polyurethane composition containing a specific aluminum compound has an excellent wet processability. It was discovered that a porous sheet material having film-forming properties, excellent surface smoothness, and low sheet density could be provided, and the present invention was achieved. That is, the present invention is a polyurethane composition consisting of polyurethane and, if necessary, a melt-combed polyurethane composition, which is characterized by containing an aluminum compound (A) represented by the formula. [In the formula, R 1 , R 2 , R 3 , and R 4 are straight chain or branched saturated or unsaturated aliphatic hydrocarbon groups having 1 to 20 carbon atoms; R is H or a straight chain having 1 to 20 carbon atoms or a branched saturated or unsaturated aliphatic hydrocarbon group. ] As the saturated or unsaturated aliphatic hydrocarbon group of R 1 , R 2 , R 3 , R 4 and R, methyl, ethyl, n

Among these, aromatic diisocyanates, particularly MDI, are practically preferred. Examples of the polymer diol (b) used in the production of polyurethane include polyether diols, polyester diols, and mixtures of two or more thereof.

3-butanediol, neopentyl glycol,
1,6-hexanediol; low-molecular-weight diols having a cyclic group [for example, those described in Japanese Patent Publication No. 1474/1974: bis(hydroxymethyl)cyclohexane, bis(hydroxyethyl)benzene, ethylene oxide adduct of bisphenol A, etc. ],
and mixtures of two or more thereof.
Examples of polyether diols having a molecular weight of 1000 or less include polytetramethylene ether glycol, polypropylene glycol, polyethylene glycol, and mixtures of two or more thereof. Dicarboxylic acids include aliphatic dicarboxylic acids (succinic acid, adipic acid, azelaic acid, sebacic acid, etc.), aromatic dicarboxylic acids (terephthalic acid,
isophthalic acid, phthalic acid, etc.), and mixtures of two or more thereof; examples of the lactone include ε-caprolactone. Polyesters can be produced by conventional methods such as adding low molecular weight diols and/or polyether diols with a molecular weight of 1000 or less to dicarboxylic acids or their ester-forming derivatives [such as anhydrides (maleic anhydride, phthalic anhydride, etc.), lower esters (terephthalic anhydride, etc.)]. (dimethyl acid, etc.), halides, etc.], or their anhydrides and alkylene oxides (e.g., ethylene oxide and/or propylene oxide), or initiators (low molecular diols and/or polyamides with a molecular weight of 1000 or less). It can be produced by adding lactone to ether diol). Preferred among these polyester diols are polyethylene adipate, polybutylene adipate,
Polyhexamethylene adipate, polyneopentyl adipate, polyethylene propylene adipate, polyethylene butylene adipate, polybutylene hexamethylene adipate, polydiethylene adipate, poly(polytetramethylene ether) adipate, polyethylene azelate, polyethylene sebacate, polybutylene azelate,
polybutylene sebacate, and polycaprolactone diol. In addition, polymer diols obtained by polymerizing these diols (polyether diols and/or polyester diols and, if necessary, low-molecular diols) and ethylenically unsaturated monomers (acrylonitrile, styrene, etc.)
54-101899, JP-A No. 54-122396), polybutadiene diol, hydroxyl group-containing vinyl polymer (acrylic diol) such as those described in JP-A-58-57413 and JP-A-57414 can also be used. . The average molecular weight of the polymeric diol (b) is usually 500~
5000, preferably 1000-3000. The chain extender (c) used as necessary during the production of the polyurethane composition includes two active hydrogen atom-containing groups (hydroxyl group, amino group, mercapro group, etc.);
A low-molecular active hydrogen compound (molecular weight: usually 500 or less, preferably 60 to 400) having preferably a hydroxyl group and/or an amino group, particularly preferably a hydroxyl group
[Low molecular diols, amino alcohols, diamines, etc.] can be used. Examples of such low-molecular active hydrogen compounds include those described in JP-A-53-42294, such as low-molecular diols [ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, butanediol,
Neopentyl glycol, hexanediol, polyethylene glycol and polypropylene glycol with a molecular weight of 200 to 400, low molecular weight diols having a cyclic group (for example, those described in Japanese Patent Publication No. 45-1474: propylene oxide adduct of bisphenol A, etc.), tertiary or quaternary nitrogen atom-containing low-molecular diols (e.g. those described in JP-A-54-130699: alkyl dialkanolamines and their quaternized products), thiodiethylene glycol, etc.]; cyamines, e.g. aliphatic Diamines (e.g. ethylene diamine), cycloaliphatic diamines (e.g. isophorone diamine), heterocyclic diamines (e.g. piperazine, aminoethylpiperazine), araliphatic diamines (e.g. xylylene diamine), aromatic diamines, hydrazine, hydrazide (adipic acid) dihydrazides, etc.); amino alcohols such as alkanolamines (monoethanolamine, monopropanolamine, etc.); and mixtures of two or more thereof. Among these, preferred are low molecular diols (especially ethylene glycol, 1,4-butanediol, neopentyl glycol, 1,6-hexanediol,
and mixtures of two or more of these). The molar ratio of the polymeric diol (b) to the chain extender (c) is usually 1:0 to 15, preferably 1:1 to 7. The overall average molecular weight of the polymeric diol (b) and chain extender (c) is usually 300 to 1000. Average molecular weight is 1000
If it is larger than 300, the wet film formability of the polyurethane decreases, and if it is smaller than 300, the wet film formability is good, but the bending resistance, particularly at low temperatures, becomes insufficient, which is not preferable. In producing polyurethane, the ratio of organic diisocyanate (a) to polymeric diol (b) and optionally chain extender (c) is such that the equivalent ratio of NCO group to active hydrogen-containing group is usually 0.9 to 1.1:1, preferably It is substantially 1. If the equivalent ratio is outside the above range, it will be difficult to obtain a polyurethane with a high degree of polymerization, which is not preferable. Polyurethane can be produced by a conventional method, such as a one-shot method in which an organic diisocyanate (a), a polymeric diol (b), and if necessary a chain extender (c) are simultaneously reacted, or (a) and (b). ) to produce an NCO-terminated prepolymer;
(c) includes a prepolymer method in which chain elongation is performed. Polyurethane production can be carried out in the presence or absence of solvents inert towards NCO groups. As such a solvent, those mentioned below can be used. When producing polyurethane, the reaction temperature is the same as the temperature normally employed in polyurethanization reactions, which is usually 20 to 100°C if a solvent is used, and usually 20 to 220°C if no solvent is used, preferably 150 to 200°C. . To accelerate the reaction, catalysts commonly used in polyurethane reactions [e.g., amine catalysts (triethylamine, N-ethylmorpholine, triethylenediamine, etc.), tin-based catalysts (trimethyltin laurate, dibutyltin dilaurate, etc.)]
can be used as needed. In addition, if necessary, polymerization terminators [such as monohydric alcohols (methanol, butanol, cyclohexanol, etc.), monovalent amines (methylamine,
butylamine, cyclohexylamine, etc.)] can also be used. Polyurethane can be produced using commonly used production equipment.
