Abstract
Provided are: a nucleating agent for a polyolefin resin having an excellent β crystal-forming effect; a nucleating agent composition for a polyolefin resin containing the nucleating agent; a polyolefin resin masterbatch; a polyolefin resin composition; a molded article of the composition; a film of the composition; a method of producing a porous film; and a package. The nucleating agent contains a compound represented by Formula (1) below wherein M represents a monovalent to trivalent metal atom having a specific gravity of 4.0 or less, or the like; a represents 1 or 2; b represents 1 or 3; x represents an integer of 1 to 3; ax=2b is satisfied; and Z represents a group represented by Formula (2) or (3) below wherein * represents a position at which each group is linked with Z of Formula (1); Y represents a direct bond or an alkylene group having 1 to 4 carbon atoms; and R1 to R10 each independently represent a hydrogen atom, a hydroxy group, a halogen atom, an alkyl group having 1 to 10 carbon atoms, or the like.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
