    Abstract: Provided are a binder in the producing of a casting sand mold according to an ink jet type lamination shaping method in which a binder is printed with respect to sand, a method for producing the binder, and a method for producing a casting sand mold using the binder. Specifically, provided are a binder useful for a casting sand mold of an ink jet type, containing: a resol-type phenolic resin that is obtained by reacting aldehydes (A1), phenols (P1), and a compound (N) having two or more phenolic hydroxyl groups in one molecule or by reacting the aldehydes (A1) and a novolac-type phenolic resin (N1), in the presence of an alkali catalyst, and has a dispersion degree (Mw/Mn) of 1.0 to 3.5 and a phenolic monomer residue of 5% or less, a method for producing the binder, and a method for producing a casting sand mold.

    Abstract: A liquid resol-type phenolic resin obtained by reacting a phenol (A), and a secondary and/or tertiary alkylamine compound (B) in the presence of a basic catalyst. The nitrogen content relative to the total weight of the liquid resol-type phenolic resin is preferably from 3 to 30% by weight. Further, the secondary and/or tertiary alkylamine compound (B) is preferably hexamethylenetetramine. Moreover, the molar ratio between the phenol (A) and the secondary and/or tertiary alkylamine compound (B) preferably satisfies (B)/(A)=0.13 to 0.35.

    Abstract: A phenol resin molding material includes a modified olefin-based polymer particle (I) and a phenol resin (II). It is preferable that the modified olefin-based polymer particle (I) satisfy at least one of the requirements (A), (B), and (C) which are defined as follows: (A) Inclusion of at least one element selected from a group consisting of a group 15 element, a group 16 element, and a group 17 element of the periodic table. (B) When the whole of the above-described olefin-based polymer particle (I) is set as 100 wt %, the content of the above-described elements is greater than or equal to 0.05 wt % and less than or equal to 50 wt %. (C) MFR which is measured under the conditions of 190° C. and 2.16 kgf based on JIS K 7210 is greater than or equal to 0.001 g/10 minutes and less than 3 g/10 minutes.
